Merge refactor/god-object-extraction (refactor step 6)

Refactor step 6. MessageLine (was MsgLine) owns the msg/addmsg/endmsg
machinery, wired to its screen, pre---More-- redraw, and input via
attach(); RogueGame keeps one-line msg/addmsgf/endmsg shorthands so
the ~400 call sites are unchanged. Player gains nextPackChar and
removeFromPack (the state half of pack.c leave_pack); leavePack keeps
only the LastPick repeat-command tracking. Level gains ObjectAt
(misc.c find_obj) and AddObject/RemoveObject/AddMonster/RemoveMonster,
replacing direct attach/detach calls on the level lists. Inventory and
pickup UI flows stay on RogueGame: display and orchestration, not
state surgery. Behavior and RNG order unchanged; suite green.

-# Build Issues Found During README Testing
-
-This document lists issues encountered when following the README.md build instructions on macOS (darwin 25.0.0, Apple Silicon).
-
-## Date
-Testing performed: Following README.md Quick Start instructions
-
-## Environment
-- **OS**: macOS (darwin 25.0.0)
-- **Architecture**: Apple Silicon (arm64)
-- **Compiler**: GCC/Clang (available)
-- **make**: Available
-- **ncurses**: Installed via Homebrew at `/opt/homebrew/opt/ncurses`
-
-## Issues Found
-
-### 1. Compilation Error: Incomplete Type 'WINDOW'
-
-**Location**: `main.c:241-242`
-
-**Error Message**:
-```
-main.c:241:11: error: incomplete definition of type 'WINDOW' (aka 'struct _win_st')
-  241 |     curscr->_cury = oy;
-      |     ~~~~~~^
-main.c:242:11: error: incomplete definition of type 'WINDOW' (aka 'struct _win_st')
-  242 |     curscr->_curx = ox;
-      |     ~~~~~~^
-```
-
-**Root Cause**:
-The code attempts to access internal ncurses structure members (`curscr->_cury` and `curscr->_curx`) which are not part of the public API in modern ncurses libraries. These internal members are not accessible in both the system ncurses and Homebrew ncurses.
-
-**Context**:
-The problematic code is in the `tstp()` function (lines 241-242), which handles stop/start signals (SIGTSTP). After resuming from a stop signal, the code tries to manually restore the cursor position by directly accessing internal ncurses structure members.
-
-**Affected Code**:
-```c
-void
-tstp(int ignored)
-{
-    // ... code ...
-    getyx(curscr, y, x);
-    mvcur(y, x, oy, ox);
-    fflush(stdout);
-    curscr->_cury = oy;  // ERROR: Internal member access
-    curscr->_curx = ox;  // ERROR: Internal member access
-}
-```
-
-**Impact**:
-- **Severity**: CRITICAL - Build fails completely
-- The game cannot be compiled on modern systems with standard ncurses
-- This affects all platforms using modern ncurses (not just macOS)
-
-**Suggested Fix**:
-1. Remove the direct structure member access (lines 241-242)
-2. The `mvcur()` call on line 239 should be sufficient for cursor positioning
-3. If cursor position tracking is needed, use public ncurses API functions like `getyx()` and `move()` instead
-
-**Workaround Attempted**:
-- Tried using Homebrew ncurses with explicit include/library paths as suggested in README troubleshooting section
-- Same error occurred with both system ncurses and Homebrew ncurses
-- Tried manual build using `Makefile.std` as documented in README (Alternative build method)
-- Same error occurred with manual build method
-- This confirms it's a code compatibility issue, not a configuration or build system issue
-
-### 2. Compiler Warnings (Non-blocking)
-
-**Location**: Multiple files
-
-**Warning Messages**:
-- `main.c`: Multiple warnings about deprecated function prototypes (C23 compatibility)
-- Function declarations without prototypes in `extern.h` conflicting with definitions
-
-**Impact**:
-- **Severity**: LOW - Warnings only, do not prevent compilation
-- Code compiles but may have issues with future C standards (C23)
-
-**Note**: These warnings are expected for legacy C code and don't prevent the build from succeeding once the critical error is fixed.
-
-## What Works
-
-1. ✅ **Configure script**: Runs successfully
-   - Detects compiler, headers, and libraries correctly
-   - Creates `config.h` and `Makefile` properly
-   - Works with both system ncurses and Homebrew ncurses paths
-
-2. ✅ **Prerequisites**: All required tools are available
-   - C compiler (gcc/clang)
-   - make
-   - ncurses library (via Homebrew)
-
-3. ✅ **Build system**: Autotools configuration works correctly
-   - `configure` script exists and is executable
-   - No need for `autoreconf` (as documented in README)
-
-## Recommendations for README Updates
-
-1. **Add Known Compatibility Issue Section**:
-   - Document that the codebase has compatibility issues with modern ncurses
-   - Note that direct access to internal ncurses structures (`curscr->_cury`, `curscr->_curx`) will fail on modern systems
-   - Provide information about which ncurses versions are known to work (if any)
-
-2. **Update macOS Troubleshooting**:
-   - The current macOS troubleshooting section mentions Homebrew ncurses paths, but this doesn't solve the compilation error
-   - Add a note that even with correct ncurses paths, the build may fail due to code compatibility issues
-
-3. **Add Build Status**:
-   - Consider adding a "Known Issues" or "Build Status" section to the README
-   - Indicate that the codebase may need patches for modern ncurses compatibility
-
-## Next Steps
-
-1. **Code Fix Required**: The `main.c` file needs to be updated to remove direct access to internal ncurses structure members
-2. **Testing**: After fix, verify the game builds and runs correctly
-3. **Documentation**: Update README with any workarounds or fixes applied
-
-## Additional Notes
-
-- The README's Quick Start instructions are clear and easy to follow
-- The build system (Autotools) is properly configured
-- The issue is specifically with code compatibility, not with the build system or documentation
-- This appears to be a known issue with porting old curses-based code to modern ncurses

+# Project Memory
+
+Working notes for agents on this repo. Read this alongside TODO.md
+(which holds the step queue and workflow) before starting work.
+
+## Error handling
+
+Panicking on bad/unexpected errors is allowed and preferred over
+threading unlikely error returns through game code — e.g. write-side
+Close/encode failures where continuing would mean corrupt state. The
+game already unwinds C's exit() calls via a gameEnd panic recovered in
+Run. Return errors where a caller genuinely handles them (save-file
+prompts, restore validation). Reserve deliberate `_ =` discards for
+true best-effort paths (scorefile writes, signal-time autosave), always
+with a comment saying why.
+
+## Linting
+
+The .golangci.yml is the house standard and may only be modified with
+sneak's explicit permission. To disable a linter, ask, explaining what
+the linter does; he approves specific exceptions, which are recorded
+in the config's "Repo-specific exceptions" block with the approval
+date. Approved so far: paralleltest (2026-07-06); testpackage,
+exhaustive, and mnd (2026-07-07). Complexity linters (cyclop, gocognit,
+nestif) stay enabled and red until refactor step 7 fixes the findings,
+per sneak 2026-07-07. Line-level //nolint
+with a reason is used sparingly for C-faithfulness (e.g. the authentic
+"missle" message spellings) and provably-safe gosec conversions; each
+needs a justifying comment.
+
+## Faithfulness
+
+Behavior must not change during the idiomatic-Go refactor unless a
+TODO step says so. The 80x24 seed-compatible gameplay, message text
+(including original typos), RNG call order, and C quirks (documented
+in tests like TestHoldScrollGreedyMonsterQuirk) are contract. Doc
+comments keep their "(file.c func_name)" breadcrumbs.
+
+## Debugging
+
+Write real, committed test files with t.Logf output and run plain
+`go test -v`; no throwaway scratch scripts. Successful debug probes
+become regression tests.

+**Rogue** is the original dungeon-crawling adventure game that spawned an

----
+The port is function-by-function faithful to the classic C sources — same
+dungeon generation (seed-compatible RNG), same combat math, same item
+tables, same messages. The C reference implementation lives on the
+`master` and `modern-rogue` branches; [ARCHITECTURE.md](ARCHITECTURE.md)
+documents both the original program structure and the design of this port.
 
-## ⚠️ About This Repository ⚠️
+## Building and running
 
-**November 2025**:
-
-I want to express my sincere appreciation to everyone who has contributed to this repository, attempted to fix issues, and forked the project over the years. When I originally created this repository in [July 2016](https://github.com/Davidslv/rogue/releases/tag/5.4.4), I was young and fascinated by this classic game. My primary intention was to archive the codebase for learning purposes, and I never expected the community engagement that followed.
-
-**Important**: I am not one of the original authors of Rogue. I am simply maintaining this repository as an archive of the original game.
-
-**Repository Policy**:
-- The **`main` branch** will remain unchanged to preserve the game exactly as it was in 1999. This ensures the original codebase remains available in its historical state.
-- For modernization efforts, bug fixes, and improvements, please use the branch: **[modern-rogue](https://github.com/Davidslv/rogue/tree/modern-rogue)**
-- You are welcome to fork this repository and make your own modifications. Many have done so over the years, and I encourage continued development in your own forks.
-
-Thank you for your interest in preserving and improving this classic game! ❤️

----
-
-## Quick Start
+Requires Go 1.25 or later and a terminal at least 80x24.
 
 ```bash
-# Configure and build
-./configure
-make
-
-# Run the game
+go build ./cmd/rogue
 ./rogue
 ```
 
-**Note**: The executable name defaults to `rogue`, but may be different if configured with `--with-program-name`. Check the output of `make` to see the actual executable name.
-
-**Note**: If you encounter compilation errors, especially related to ncurses compatibility, see [BUILD_ISSUES.md](BUILD_ISSUES.md) for known issues and workarounds.
-
----
-
-## Prerequisites
-
-### Required
-
-- **C Compiler**: GCC or Clang (C89/C90 compatible)
-- **make**: Build automation tool (usually pre-installed)
-  - **Linux**: Usually pre-installed, or `sudo apt-get install build-essential` (Debian/Ubuntu)
-  - **macOS**: Included with Xcode Command Line Tools (`xcode-select --install`)
-  - **FreeBSD**: `pkg install gmake` (or use `gmake` instead of `make`)
-- **ncurses library**: For terminal-based graphics
-  - **Linux**: `sudo apt-get install libncurses5-dev` (Debian/Ubuntu)
-  - **Linux**: `sudo yum install ncurses-devel` (RHEL/CentOS/Fedora)
-  - **macOS**: `brew install ncurses` (Homebrew)
-  - **FreeBSD**: `pkg install ncurses`
-
-### Optional (for building from source)
-
-- **Autotools**: autoconf, automake, m4 (needed if `configure` script doesn't exist)
-  - **Linux**: `sudo apt-get install autoconf automake m4` (Debian/Ubuntu)
-  - **Linux**: `sudo yum install autoconf automake m4` (RHEL/CentOS/Fedora)
-  - **macOS**: Usually pre-installed with Xcode Command Line Tools, or `brew install autoconf automake`
-  - **FreeBSD**: `pkg install autoconf automake m4`
-  - **Note**: If the `configure` script already exists in the repository, you don't need these tools
-
-### Optional (for building documentation)
-
-- **Documentation tools**: groff/nroff, tbl, colcrt, sed (for generating man pages and docs)
-  - **Linux**: Usually pre-installed, or `sudo apt-get install groff` (Debian/Ubuntu)
-  - **macOS**: Usually pre-installed
-  - **Note**: Documentation can be built later with `make` if these tools are available
-  - **Note**: Generated documentation (man pages, HTML, etc.) is adapted to match the actual codebase outcomes and build configuration (e.g., executable name, scoreboard file location)
-
-### Platform Support
-
-This codebase supports multiple platforms:
-- **Unix-like systems** (Linux, macOS, FreeBSD, etc.)
-- **Windows** (via Visual Studio project files or MinGW/MSYS2)
-- **DOS** (DJGPP)
-- **Cygwin**
-
----
-
-## Building from Source
-
-### Standard Build (Recommended)
-
-The project uses Autotools for configuration. The build process depends on whether the `configure` script already exists:
-
-**If `configure` script exists** (most common case):
 ```bash
-# Configure the build system
-./configure
-
-# Compile
-make
-
-# Optional: Install system-wide (requires root)
-sudo make install
-```
-
-**If `configure` script does NOT exist** (e.g., fresh git clone without generated files):
-```bash
-# Generate configure script (requires autoconf, automake, m4)
-autoreconf -fiv
-
-# Configure the build system
-./configure
-
-# Compile
-make
-
-# Optional: Install system-wide (requires root)
-sudo make install
-```
-
-**Note**: Most source distributions include the `configure` script, so you typically only need `autoreconf` if you're building directly from a git repository that doesn't include generated files.
-
-**Note**: The executable name and other build outputs are determined by the `configure` script based on the codebase configuration. If you're using `Makefile.std` directly (manual build), the default executable name is `rogue54`, whereas `configure` defaults to `rogue`. Always check the actual output of your build process to confirm the executable name.
-
-### Configure Options
-
-The `configure` script supports several options:
-
-```bash
-# Enable wizard mode (debug/cheat mode)
-./configure --enable-wizardmode
-
-# Set custom scoreboard file location
-./configure --enable-scorefile=/path/to/scoreboard.scr
-
-# Disable scoreboard
-./configure --enable-scorefile=no
-
-# Set custom program name
-./configure --with-program-name=myrogue
-
-# Install as setgid (for shared scoreboard)
-./configure --enable-setgid=games
-
-# See all options
-./configure --help
-```
-
-### Manual Build (Without Autotools)
-
-If you prefer to build manually or the configure script fails:
-
-**Option 1: Using Makefile.std**
-```bash
-# Build using the standard Makefile
-make -f Makefile.std
-
-# Note: This creates 'rogue54' by default (see Makefile.std to change)
-```
-
-**Option 2: Direct compilation**
-```bash
-# Compile directly (may need additional defines)
-gcc -O2 -o rogue *.c -lcurses
-
-# Or with more defines (see Makefile.std for full list):
-gcc -O2 -DALLSCORES -DSCOREFILE=\"rogue.scr\" -DLOCKFILE=\"rogue.lck\" -o rogue *.c -lcurses
-```
-
-**Note**:
-- Manual builds may require additional defines. See `Makefile.std` for reference.
-- The executable name may differ (`rogue` vs `rogue54` depending on build method).
-- You may need to adjust include paths if ncurses is in a non-standard location.
-
-### Windows Build
-
-#### Using Visual Studio
-
-1. **Install PDCurses**:
-   - Download PDCurses from https://pdcurses.org/
-   - Extract to a directory (e.g., `C:\pdcurses`)
-   - Build PDCurses library following its instructions
-
-2. **Configure Visual Studio project**:
-   - Open `rogue54.sln` in Visual Studio
-   - Update include/library paths in project settings to point to your PDCurses installation
-   - Ensure PDCurses library is linked (check project properties → Linker → Input)
-
-3. **Build the solution**: Build → Build Solution (or press F7)
-
-**Alternative**: If PDCurses is in a peer directory (`../pdcurses/`), the project may work without modification.
-
-#### Using MinGW/MSYS2
-
-```bash
-# Install ncurses via MSYS2
-pacman -S mingw-w64-x86_64-ncurses
-
-# Configure and build
-./configure
-make
-```
-
-**Note**: For MinGW/MSYS2, you may need to use `mingw32-make` instead of `make` depending on your installation.

-## Development Guide
-
-### Code Style
-
-This codebase follows classic C (pre-C99) conventions:
-
-- Uses `register` keyword for frequently accessed variables
-- Custom macros for control flow (`when`, `otherwise`, `on()`, etc.)
-- Linked lists for dynamic data structures
-- Bit flags for object/monster states
-- Function declarations in headers, definitions in `.c` files
-
-### Key Data Structures
-
-#### `THING` (union)
-Represents both monsters and objects:
-```c
-union thing {
-    struct {  // Monster/player
-        coord t_pos;
-        struct stats t_stats;
-        short t_flags;
-        // ...
-    } _t;
-    struct {  // Object
-        int o_type;
-        int o_which;
-        int o_hplus, o_dplus;
-        // ...
-    } _o;
-};
-```
-
-#### `PLACE`
-Represents a map cell:
-```c
-typedef struct {
-    char p_ch;        // Character to display
-    char p_flags;     // Flags (seen, passage, etc.)
-    THING *p_monst;   // Monster at this location
-} PLACE;
-```
-
-### Game Loop Flow
-
-```
-main()
-  ├─> Initialize (curses, player, objects)
-  ├─> new_level()      # Generate first level
-  ├─> Start daemons    # Background processes
-  └─> playit()
-       └─> while(playing)
-            └─> command()
-                 ├─> do_daemons(BEFORE)
-                 ├─> Read input
-                 ├─> Execute command
-                 ├─> do_daemons(AFTER)
-                 └─> Monster movement
-```
-
-### Daemons and Fuses
-
-**Daemons** are background processes that run every turn:
-- `runners()` - Monster movement
-- `doctor()` - Health regeneration
-- `stomach()` - Hunger system
-- `swander()` - Wandering monsters
-
-**Fuses** are one-time delayed actions:
-- Used for temporary effects (haste, confusion, etc.)
-
-### Adding New Features
-
-1. **New Monster Type**:
-   - Add entry to `monsters[]` array in `monsters.c`
-   - Update monster generation logic in `new_level.c`
-
-2. **New Item Type**:
-   - Add type constant to `rogue.h`
-   - Add info structure (e.g., `pot_info[]` for potions)
-   - Implement effect in corresponding file (e.g., `potions.c`)
-
-3. **New Command**:
-   - Add case in `command()` function in `command.c`
-   - Implement handler function
-
-### Debugging
-
-#### Enable Wizard Mode
-
-```bash
-./configure --enable-wizardmode
-make
-./rogue ""  # Empty string enables wizard password prompt
-```
-
-Wizard mode provides:
-- See all monsters (`SEEMONST` flag)
-- Set dungeon seed via `SEED` environment variable
-- Debug commands (see `wizard.c`)
-
-#### Compile with Debug Symbols
-
-```bash
-./configure CFLAGS="-g -O0"
-make
-gdb ./rogue
-```
-
-### Testing
-
-```bash
-# Test death screen
-./rogue -d
-
-# Test scoreboard
-./rogue -s
-
-# Test save/restore
-./rogue
-# Play a bit, save (S command), quit
-./rogue ~/rogue.save  # Should restore
-```

-
-## Troubleshooting
-
-**Note**: For detailed information about known build issues, especially on modern systems, see [BUILD_ISSUES.md](BUILD_ISSUES.md).
-
-### Build Issues
-
-**Problem**: `configure: error: curses library not found`
-
-**Solution**: Install ncurses development package:
-```bash
-# Debian/Ubuntu
-sudo apt-get install libncurses5-dev
-
-# RHEL/CentOS/Fedora
-sudo yum install ncurses-devel
-
-# macOS
-brew install ncurses
-```
-
-**Problem**: `autoreconf: command not found` or `autoconf: command not found`
-
-**Solution**: Install autotools (only needed if `configure` script doesn't exist):
-```bash
-# Debian/Ubuntu
-sudo apt-get install autoconf automake m4
-
-# RHEL/CentOS/Fedora
-sudo yum install autoconf automake m4
-
-# macOS (usually pre-installed with Xcode)
-xcode-select --install
-# Or via Homebrew:
-brew install autoconf automake
-
-# FreeBSD
-pkg install autoconf automake m4
-```
-
-**Note**: If the `configure` script already exists, you don't need these tools. Only run `autoreconf` if you're building from a git repository without generated files.
-
-**Problem**: Compilation errors about undefined functions
-
-**Solution**: Ensure `configure` was run successfully and `config.h` exists:
-```bash
-./configure
-make clean
-make
-```
-
-**Problem**: Compilation errors about incomplete type 'WINDOW' or `curscr->_cury` / `curscr->_curx`
-
-**Solution**: This is a known compatibility issue with modern ncurses. The codebase attempts to access internal ncurses structure members that are not available in modern ncurses libraries. See [BUILD_ISSUES.md](BUILD_ISSUES.md) for detailed information about this issue and potential fixes.
-
-**Problem**: `make: command not found`
-
-**Solution**: Install make:
-```bash
-# Debian/Ubuntu
-sudo apt-get install build-essential
-
-# RHEL/CentOS/Fedora
-sudo yum groupinstall "Development Tools"
-
-# macOS
-xcode-select --install
-
-# FreeBSD (use gmake)
-pkg install gmake
-# Then use: gmake instead of make
-```
-
-**Problem**: `configure: error: cannot find install-sh or install.sh`
-
-**Solution**: The `install-sh` script should be in the repository. If missing, you may need to regenerate it:
-```bash
-autoreconf -fiv
-```
-
-**Problem**: Documentation build fails (missing groff/nroff/tbl)
-
-**Solution**: Documentation tools are optional. The game will build without them, but man pages won't be generated:
-```bash
-# Install documentation tools (optional)
-# Debian/Ubuntu
-sudo apt-get install groff
-
-# RHEL/CentOS/Fedora
-sudo yum install groff
-
-# Or skip documentation generation - the game will still build
-```
-
-### Runtime Issues
-
-**Problem**: Screen is too small
-
-**Solution**: Rogue requires at least 24x80 terminal. Resize your terminal or use a larger font.
-
-**Problem**: Terminal doesn't support colors/features
-
-**Solution**: The game will auto-detect terminal capabilities. For best experience, use a modern terminal emulator (xterm, gnome-terminal, iTerm2, etc.).
-
-**Problem**: Save file corruption
-
-**Solution**: Save files are encrypted. Don't edit them manually. If corrupted, delete `~/rogue.save` and start fresh.
-
-**Problem**: Scoreboard permission errors
-
-**Solution**: If using setgid installation:
-```bash
-sudo chgrp games rogue.scr
-sudo chmod 664 rogue.scr
-```
-
-### Platform-Specific
-
-**Windows (MinGW)**: Ensure PDCurses is properly linked. Check `LIBS` in Makefile.
-
-**macOS**: If using Homebrew ncurses, you may need to specify include/library paths:
-```bash
-# For Intel Macs (Homebrew in /usr/local)
-./configure CPPFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib"
-
-# For Apple Silicon Macs (Homebrew in /opt/homebrew)
-./configure CPPFLAGS="-I/opt/homebrew/include" LDFLAGS="-L/opt/homebrew/lib"

+# Status
+
+pre-1.0
+
+The port on main is complete and faithful (function-by-function from
+Rogue 5.4.4 C; reference sources on c-master/modern-rogue). Current
+phase: refactor from a transliterated port into idiomatic Go — one
+feature branch per step below, descriptive naming, real types, house
+style per ~/dev/prompts/prompts/CODE_STYLEGUIDE_GO.md.
+
+Refactor ground rules:
+
+- Behavior must not change unless a step says so. The full test suite
+  (scripted sessions, generation invariants, C-compatible RNG goldens)
+  gates every step; 80x24 seed-compatible gameplay stays intact.
+- Renames keep the C lineage greppable: doc comments retain their
+  "(file.c func_name)" breadcrumbs, and the docs refresh step adds a
+  C-name → Go-name table to ARCHITECTURE.md.
+
+# Next Step
+
+Refactor step 7: effects dispatch — the giant quaff/readScroll/doZap
+switches become per-kind handler tables of small named methods,
+keeping effect order and RNG call sequence identical. This step also
+clears the outstanding cyclop/gocognit/nestif lint findings.
+
+# Completed Steps
+
+- 2026-07-07 Refactor step 6 (refactor/god-object-extraction):
+  MessageLine (was MsgLine) owns the msg/addmsg/endmsg machinery,
+  wired to its screen/look/input needs via attach(); RogueGame keeps
+  one-line msg/addmsgf/endmsg shorthands so call sites are unchanged.
+  Player owns pack bookkeeping (nextPackChar, removeFromPack — the
+  state half of leave_pack; leavePack keeps only LastPick tracking).
+  Level owns object/monster list management and lookup (ObjectAt
+  replaces findObj; AddObject/RemoveObject/AddMonster/RemoveMonster
+  replace direct attachObj/detachObj/attachMon/detachMon on level
+  lists). Inventory/pickup UI flows stay on RogueGame deliberately:
+  they are display and turn orchestration, not state surgery.
+
+- 2026-07-07 Refactor step 5 (refactor/item-combat-ui-renames, three
+  commits, one subsystem each): items — getItem→promptPackItem now
+  returning (obj, ok), invName→inventoryName, doPot→applyPotionFuse;
+  combat — rollEm→rollAttacks, attack/moveMonster/chaseStep return
+  (removed bool) instead of C -1/0 int codes; UI —
+  getDir→promptDirection. C breadcrumbs kept; suite green.
+
+- 2026-07-07 Refactor step 4 (refactor/movement-renames): movement/world
+  renames (doMove→moveHero, beTrapped→springTrap, rndmove→randomStep,
+  doRooms/doPassages/doMaze→digRooms/digPassages/digMaze,
+  chgStr→changeStrength, doRun→startRun, moveStuff→finishMove,
+  turnref→turnRefresh, moveMonst→moveMonster, doChase→chaseStep,
+  setOldch→setOldChar, cansee→canSee, roomin→roomIn, runto→runTo,
+  conn→connectRooms, putpass→putPassage, passnum→numberPassages,
+  numpass→numberPassage, rndPos→randomPos, rndRoom→randomRoom,
+  treasRoom→treasureRoom, accntMaze→accountMaze); all goto/label flows
+  replaced with loops (moveHero retry loop + extracted passageTurn,
+  dispatch re-dispatch loop, chaseStep passage loop, saveGame labeled
+  prompt loop); C breadcrumbs kept in doc comments.
+- 2026-07-07 Lint adoption finished (refactor/no-package-globals): all
+  37 package-level vars moved into `gameData` (built by `newGameData`,
+  hung on RogueGame as `g.data`, set in NewGame and Restore); ObjectKind
+  Glyph()/objectKindForGlyph became switches; the table-reading subtype
+  Stringers were removed; isMagic became a RogueGame method; goconst
+  fixed with named word constants (potionName, goldName, staffName,
+  ripWall, ...); testpackage and exhaustive disabled in .golangci.yml
+  with sneak's approval (2026-07-07); misspell's corruption of the
+  "ther" scroll syllable reverted. mnd disabled with sneak's approval
+  (2026-07-07, follow-up commit). Remaining red: cyclop (36), nestif
+  (30), gocognit (23) stay until step 7 fixes them per sneak's ruling.
+- 2026-07-06 Lint adoption bulk (refactor/lint-adoption, 5ba9fe8):
+  .golangci.yml copied verbatim from the prompts repo (plus the
+  sneak-approved paralleltest exception, 2026-07-06); ~1,500 findings
+  fixed (autofix formatting sweep, errcheck/err113/noinlineerr error
+  handling, forbidigo, funcorder, recvcheck pointer receivers,
+  goprintffuncname renames msg helpers to *f, revive doc comments,
+  gocritic switch rewrites, gosec real fixes plus justified nolints,
+  unparam signature tightening, C-faithful "missle" spellings restored
+  after misspell autofix changed game text).
+- 2026-07-06 Module base path updated to git.eeqj.de/sneak/rgoue
+  (go.mod, term/ and cmd/ imports, ARCHITECTURE.md, version string).
+- 2026-07-06 Refactor step 3 (refactor/object-fields): Object.Arm split
+  into ArmorClass/Charges/GoldValue/Bonus (rings); Stats.Arm →
+  ArmorClass; damage strings parsed once into DiceSpec at table
+  definition (ParseDice keeps C roll_em parse semantics, incl. "%%%x0"
+  and "000x0" edge cases, regression-tested); save format 5.4.4-go3.
+- 2026-07-06 Refactor step 2 (refactor/typed-kinds, b940cfc):
+  ObjectKind separates item category from map glyph (Object.Type byte
+  → Kind ObjectKind with Glyph()); PotionKind/ScrollKind/RingKind/
+  WandKind/WeaponKind/ArmorKind/TrapKind typed iota enums with
+  Stringer; typed accessors on Object; getItem/inventory/whatis
+  filters take ObjectKind (KindCallable/KindRingOrStick replace
+  CALLABLE/R_OR_S); save format bumped to 5.4.4-go2. Suite green.
+- 2026-07-06 Refactor step 1 (refactor/descriptive-constants): renamed
+  all flag bits, trap types, item subtype constants, and Max* counts to
+  descriptive names (IsHuh→Confused, SeeMonst→SenseMonsters,
+  WsHasteM→WandHasteMonster, MaxSticks→NumWandTypes, ...);
+  Level.NTraps→TrapCount; C names kept as comment breadcrumbs. Pure
+  rename, suite green.
+- 2026-07-06 Made the rgoue branch Go-only: removed C sources and the
+  autoconf/VS build system (they remain on master and modern-rogue),
+  ported the last wizard command (item-probability listing), rewrote
+  README.md for the Go port (c0b533e)
+- 2026-07-06 Ported the command loop, save/restore, the tcell terminal
+  layer, and the playable binary at cmd/rogue (41fc104)
+- 2026-07-06 Ported item effects: potions, scrolls, options, call_it
+  (cdf9bf7)
+- 2026-07-06 Ported combat, the chase driver, traps, zapping, death and
+  scores (3c5add8)
+- 2026-07-06 Ported dungeon generation, base items, the pack, and
+  monster creation (a69ef7d)
+- 2026-07-06 Ported the foundation: types, seed-compatible RNG, item
+  tables, daemon scheduler (7fa2048)
+- 2026-07-06 Wrote ARCHITECTURE.md Parts 1 and 2: complete map of the C
+  program and the Go port design (91eeee0, 45dba95)
+- Fork base: Davidslv/rogue C 5.4.4 with modernization fixes (C23
+  prototypes, ncurses compat), preserved on master/modern-rogue
+
+# Future Steps
+
+1. Refactor step 8: constructor and style pass per the house
+   styleguide — game.New(game.Params{...}) replacing NewGame(Config);
+   replace the gameEnd panic unwind with error-based turn results where
+   feasible; 77-column wrap sweep.
+2. Docs refresh: update ARCHITECTURE.md Part 2 and README.md for the
+   post-refactor names; add the C name → Go name rename table.
+3. Playtest hardening pass: play several full games with the tcell
+   binary and extend run_test.go to script a deeper multi-level
+   playthrough (descend past level 5, use potions, scrolls, zapping,
+   save/restore). Fix any panics, message mismatches, or divergences
+   from the C behavior that this uncovers, with regression tests.
+4. Verify the seed-compatibility claim against the C reference on
+   c-master: same seed, same dungeon, same item tables, for several
+   seeds.
+5. Broaden unit test coverage where playtesting finds thin spots
+   (rings, sticks, wizard commands).
+6. Tag a release once a full game (Amulet retrieval and score entry)
+   completes without defects.
+7. Full-terminal-size support (deferred by explicit decision
+   2026-07-06): per-game dungeon dimensions instead of the 80x24
+   constants; open design questions are resize policy, gameplay
+   tuning at larger sizes, and a --classic 80x24 mode.
+8. Note: this repo is exempt from the standard policy scaffold. Do not
+   add Makefile, Dockerfile, or REPO_POLICIES.md.

- * The various tuneable defines are:
- *
- *	SCOREFILE	Where/if the score file should live.
- *	ALLSCORES	Score file is top ten scores, not top ten
- *			players.  This is only useful when only a few
- *			people will be playing; otherwise the score file
- *			gets hogged by just a few people.
- *	NUMSCORES	Number of scores in the score file (default 10).
- *	NUMNAME		String version of NUMSCORES (first character
- *			should be capitalized) (default "Ten").
- *	MAXLOAD		What (if any) the maximum load average should be
- *			when people are playing.  Since it is divided
- *			by 10, to specify a load limit of 4.0, MAXLOAD
- *			should be "40".	 If defined, then
- *      LOADAV		Should it use it's own routine to get
- *		        the load average?
- *      NAMELIST	If so, where does the system namelist
- *		        hide?
- *	MAXUSERS	What (if any) the maximum user count should be
- *	                when people are playing.  If defined, then
- *      UCOUNT		Should it use it's own routine to count
- *		        users?
- *      UTMP		If so, where does the user list hide?
- *	CHECKTIME	How often/if it should check during the game
- *			for high load average.

-                          ABSTRACT
-
-    Rogue  is a visual CRT based fantasy game which runs
-    under the UNIX timesharing system.  This  paper  de-
-    scribes how to play rogue, and gives a few hints for
-    those who might otherwise get lost in  the  Dungeons
-    of Doom.
-
-
-
-
-1.  Introduction
-
-     You  have  just finished your years as a student at the
-local fighter's guild.  After much practice  and  sweat  you
-have finally completed your training and are ready to embark
-upon a perilous adventure.  As a test of  your  skills,  the
-local  guildmasters have sent you into the Dungeons of Doom.
-Your task is to return with  the  Amulet  of  Yendor.   Your
-reward  for  the completion of this task will be a full mem-
-bership in the local guild.  In addition, you are allowed to
-keep all the loot you bring back from the dungeons.
-
-     In  preparation  for  your  journey,  you  are given an
-enchanted mace, a bow, and a quiver of arrows taken  from  a
-dragon's  hoard in the far off Dark Mountains.  You are also
-outfitted with elf-crafted armor and given  enough  food  to
-reach  the  dungeons.  You say goodbye to family and friends
-for what may be the last time and head up the road.
-
-     You set out on your way to the dungeons and after  sev-
-eral  days  of  uneventful travel, you see the ancient ruins
-that mark the entrance to the Dungeons of Doom.  It is  late
-at  night,  so  you  make camp at the entrance and spend the

-night sleeping under the open skies.   In  the  morning  you
-gather  your  weapons, put on your armor, eat what is almost
-your last food, and enter the dungeons.
-
-2.  What is going on here?
-
-     You have just begun a game of rogue.  Your goal  is  to
-grab as much treasure as you can, find the Amulet of Yendor,
-and get out of the Dungeons of Doom alive.  On the screen, a
-map  of  where  you  have been and what you have seen on the
-current dungeon level is kept.  As you explore more  of  the
-level, it appears on the screen in front of you.
-
-     Rogue  differs from most computer fantasy games in that
-it  is  screen  oriented.   Commands  are  all  one  or  two
-keystrokes1  and  the results of your commands are displayed
-graphically on the screen rather  than  being  explained  in
-words.2
-
-     Another  major  difference between rogue and other com-
-puter fantasy games is that once you  have  solved  all  the
-puzzles  in a standard fantasy game, it has lost most of its
-excitement and it ceases to be fun.   Rogue,  on  the  other
-hand,  generates  a  new  dungeon every time you play it and
-even the author finds it an entertaining and exciting  game.
-
-3.  What do all those things on the screen mean?
-
-     In  order  to  understand what is going on in rogue you
-have to first get some grasp of what rogue is doing with the
-screen.   The  rogue  screen is intended to replace the "You
-can see ..." descriptions of standard fantasy games.  Figure
-1 is a sample of what a rogue screen might look like.
-
-3.1.  The bottom line
-
-     At  the  bottom  line of the screen are a few pieces of
-cryptic information describing your current status.  Here is
-an explanation of what these things mean:
-
-Level  This  number  indicates how deep you have gone in the
-       dungeon.  It starts at one and  goes  up  as  you  go
-       deeper into the dungeon.
-
-Gold   The  number  of  gold pieces you have managed to find
-       and keep with you so far.
-____________________
-   1 As opposed to pseudo English sentences.
-   2  A minimum screen size of 24 lines by 80 columns is re-
-quired.  If the screen is larger,  only  the  24x80  section
-will be used for the map.

-
-Hp     Your  current  and  maximum  health  points.   Health
-       points  indicate  how much damage you can take before
-       you die.  The more you get hit in a fight, the  lower
-       they  get.   You can regain health points by resting.
-       The number in parentheses is the maximum number  your
-       health points can reach.
-
-Str    Your  current  strength  and  maximum  ever strength.
-       This can be any integer less than or equal to 31,  or
-       greater  than or equal to three.  The higher the num-
-       ber, the stronger you are.  The number in the  paren-
-       theses  is  the maximum strength you have attained so
-       far this game.
-
-Arm    Your current armor protection.  This number indicates
-       how  effective  your  armor is in stopping blows from
-       unfriendly creatures.  The higher this number is, the
-       more effective the armor.
-
-Exp    These  two numbers give your current experience level
-       and experience points.  As you do  things,  you  gain
-       experience   points.   At  certain  experience  point
-       totals, you gain an experience level.  The more expe-
-       rienced you are, the better you are able to fight and
-       to withstand magical attacks.
-
-3.2.  The top line
-
-     The top line of the screen  is  reserved  for  printing
-messages  that describe things that are impossible to repre-
-sent visually.  If you see a "--More--"  on  the  top  line,
-this  means that rogue wants to print another message on the
-screen, but it wants to make certain that you have read  the
-one  that  is  there  first.  To read the next message, just

-type a space.
-
-3.3.  The rest of the screen
-
-     The rest of the screen is the map of the level  as  you
-have  explored  it so far.  Each symbol on the screen repre-
-sents something.  Here is a list of what the various symbols
-mean:
-
-@    This symbol represents you, the adventurer.
-
--|   These symbols represent the walls of rooms.
-
-+    A door to/from a room.
-
-.    The floor of a room.
-
-#    The floor of a passage between rooms.
-
-*    A pile or pot of gold.
-
-)    A weapon of some sort.
-
-]    A piece of armor.
-
-!    A flask containing a magic potion.
-
-?    A piece of paper, usually a magic scroll.
-
-=    A ring with magic properties
-
-/    A magical staff or wand
-
-^    A trap, watch out for these.
-
-%    A staircase to other levels
-
-:    A piece of food.
-
-A-Z  The uppercase letters represent the various inhabitants
-     of the Dungeons of Doom.  Watch out, they can be  nasty
-     and vicious.
-
-4.  Commands
-
-     Commands  are given to rogue by typing one or two char-
-acters.  Most commands can be preceded by a count to  repeat
-them (e.g. typing "10s" will do ten searches).  Commands for
-which counts make no sense have the count ignored.  To  can-
-cel  a  count  or a prefix, type <ESCAPE>.  The list of com-
-mands is rather long, but it can be read at any time  during
-the  game  with the "?"  command.  Here it is for reference,
-with a short explanation of each command.

-

-

-
-
-?    The help command.  Asks for a character  to  give  help
-     on.   If you type a "*", it will list all the commands,
-     otherwise it will explain what the character you  typed
-     does.
-
-/    This  is  the "What is that on the screen?" command.  A
-     "/" followed by any  character  that  you  see  on  the
-     level,  will  tell  you  what  that  character is.  For
-     instance, typing "/@" will tell you that the "@" symbol
-     represents you, the player.
-
-h, H, ^H
-     Move left.  You move one space to the left.  If you use
-     upper case "h", you will continue to  move  left  until
-     you  run  into  something.  This works for all movement
-     commands (e.g.  "L" means run in direction "l") If  you
-     use  the "control" "h", you will continue moving in the
-     specified direction until you pass something  interest-
-     ing  or  run  into  a wall.  You should experiment with
-     this, since it is a very useful command, but very  dif-
-     ficult  to  describe.  This also works for all movement
-     commands.
-
-j    Move down.
-
-k    Move up.
-
-l    Move right.
-
-y    Move diagonally up and left.
-
-u    Move diagonally up and right.
-
-b    Move diagonally down and left.
-
-n    Move diagonally down and right.
-
-t    Throw an object.  This is a prefix command.  When  fol-
-     lowed with a direction it throws an object in the spec-
-     ified direction.  (e.g. type "th" to throw something to
-     the left.)
-
-f    Fight  until someone dies.  When followed with a direc-
-     tion this will force you to fight the creature in  that
-     direction until either you or it bites the big one.
-
-m    Move  onto  something without picking it up.  This will
-     move you one space in the direction you specify and, if
-     there  is  an object there you can pick up, it won't do
-     it.
-
-z    Zap prefix.  Point a staff or wand in a given direction
-     and  fire  it.   Even  non-directional  staves  must be

-
-     pointed in some direction to be used.
-
-^    Identify trap command.  If a trap is on  your  map  and
-     you  can't  remember what type it is, you can get rogue
-     to remind you by getting next to it and typing "^" fol-
-     lowed  by  the  direction that would move you on top of
-     it.
-
-s    Search for traps and secret doors.  Examine each  space
-     immediately adjacent to you for the existence of a trap
-     or secret door.  There is a large chance that  even  if
-     there  is  something  there,  you won't find it, so you
-     might have to search a while before you find something.
-
->    Climb down a staircase to the next level.  Not surpris-
-     ingly, this can only be done if  you  are  standing  on
-     staircase.
-
-<    Climb up a staircase to the level above.  This can't be
-     done without the Amulet of Yendor in your possession.
-
-.    Rest.  This is the "do nothing" command.  This is  good
-     for waiting and healing.
-
-,    Pick up something.  This picks up whatever you are cur-
-     rently standing on, if you are standing on anything  at
-     all.
-
-i    Inventory.  List what you are carrying in your pack.
-
-I    Selective  inventory.   Tells you what a single item in
-     your pack is.
-
-q    Quaff one of the potions you are carrying.
-
-r    Read one of the scrolls in your pack.
-
-e    Eat food from your pack.
-
-w    Wield a weapon.  Take a weapon out  of  your  pack  and
-     carry  it  for use in combat, replacing the one you are
-     currently using (if any).
-
-W    Wear armor.  You can only wear one suit of armor  at  a
-     time.  This takes extra time.
-
-T    Take armor off.  You can't remove armor that is cursed.
-     This takes extra time.
-
-P    Put on a ring.  You can wear only two rings at  a  time
-     (one  on  each hand).  If you aren't wearing any rings,
-     this command will ask you which hand you want  to  wear
-     it  on, otherwise, it will place it on the unused hand.
-

-
-
-     The program assumes that you wield your sword  in  your
-     right hand.
-
-R    Remove  a ring.  If you are only wearing one ring, this
-     command takes it off.  If you are wearing two, it  will
-     ask you which one you wish to remove,
-
-d    Drop  an  object.   Take something out of your pack and
-     leave it lying on  the  floor.   Only  one  object  can
-     occupy  each space.  You cannot drop a cursed object at
-     all if you are wielding or wearing it.
-
-c    Call an object something.  If you have a type of object
-     in  your  pack  which  you  wish  to remember something
-     about, you can use the call command to give a  name  to
-     that  type  of  object.   This is usually used when you
-     figure out what a potion, scroll,  ring,  or  staff  is
-     after  you  pick  it  up,  or when you want to remember
-     which of those swords in your pack you were wielding.
-
-D    Print out  which  things  you've  discovered  something
-     about.   This  command  will ask you what type of thing
-     you are interested in.  If you type the character for a
-     given  type  of  object (e.g.  "!"  for potion) it will
-     tell you which kinds of that type of object you've dis-
-     covered  (i.e.,  figured out what they are).  This com-
-     mand works for potions, scrolls, rings, and staves  and
-     wands.
-
-o    Examine  and  set  options.   This  command  is further
-     explained in the section on options.
-
-^R   Redraws the screen.  Useful  if  spurious  messages  or
-     transmission errors have messed up the display.
-
-^P   Print  last  message.  Useful when a message disappears
-     before you can read it.  This  only  repeats  the  last
-     message  that  was  not  a mistyped command so that you
-     don't loose anything by accidentally typing  the  wrong
-     character instead of ^P.
-
-<ESCAPE>
-     Cancel a command, prefix, or count.
-
-!    Escape to a shell for some commands.
-
-Q    Quit.  Leave the game.
-
-S    Save  the  current  game  in  a  file.  It will ask you
-     whether you wish to use the default save file.  Caveat:
-     Rogue  won't  let  you start up a copy of a saved game,
-     and it removes the save file as soon as you start up  a
-     restored game.  This is to prevent people from saving a

-5.  Rooms
-
-     Rooms in the dungeons are either lit or dark.   If  you
-walk  into  a lit room, the entire room will be drawn on the
-screen as soon as you enter.  If you walk into a dark  room,
-it will only be displayed as you explore it.  Upon leaving a
-room, all monsters inside  the  room  are  erased  from  the
-screen.   In  the darkness you can only see one space in all
-directions around you.  A corridor is always dark.
-
-6.  Fighting
-
-     If you see a monster and you wish  to  fight  it,  just
-attempt  to run into it.  Many times a monster you find will
-mind its own business unless you attack it.  It is often the
-case that discretion is the better part of valor.
-
-7.  Objects you can find
-
-     When you find something in the dungeon, it is common to
-want to pick the object up.  This is accomplished  in  rogue
-by  walking  over the object (unless you use the "m" prefix,
-see above).  If you are carrying too many things,  the  pro-
-gram  will  tell you and it won't pick up the object, other-
-wise it will add it to your pack and tell you what you  just
-picked up.
-
-     Many  of  the  commands  that  operate  on objects must
-prompt you to find out which object you want to use.  If you
-change  your  mind  and  don't want to do that command after
-all, just type an <ESCAPE> and the command will be  aborted.
-
-     Some  objects,  like armor and weapons, are easily dif-
-ferentiated.  Others, like scrolls and  potions,  are  given
-labels which vary according to type.  During a game, any two

-
-
-
-A Guide to the Dungeons of Doom                     USD:33-9
-
-
-of the same kind of object with the same label are the  same
-type.  However, the labels will vary from game to game.
-
-     When  you  use  one  of  these  labeled objects, if its
-effect is obvious, rogue will remember what it is  for  you.
-If  it's  effect  isn't  extremely obvious you will be asked
-what you want to scribble on it so  you  will  recognize  it
-later, or you can use the "call" command (see above).
-
-7.1.  Weapons
-
-     Some  weapons,  like  arrows, come in bunches, but most
-come one at a time.  In order to  use  a  weapon,  you  must
-wield  it.   To  fire  an arrow out of a bow, you must first
-wield the bow, then throw the arrow.  You can only wield one
-weapon  at  a  time, but you can't change weapons if the one
-you are currently wielding is cursed.  The commands  to  use
-weapons are "w" (wield) and "t" (throw).
-
-7.2.  Armor
-
-     There  are  various  sorts of armor lying around in the
-dungeon.  Some of it is enchanted, some is cursed, and  some
-is  just normal.  Different armor types have different armor
-protection.  The higher the armor protection, the more  pro-
-tection  the  armor  affords  against the blows of monsters.
-Here is a list of the various armor types and  their  normal
-armor protection:
-
-
-           +-----------------------------------------+
-           |  Type                        Protection |
-           |None                                   0 |
-           |Leather armor                          2 |
-           |Studded leather / Ring mail            3 |
-           |Scale mail                             4 |
-           |Chain mail                             5 |
-           |Banded mail / Splint mail              6 |
-           |Plate mail                             7 |
-           +-----------------------------------------+
-
-
-If  a piece of armor is enchanted, its armor protection will
-be higher than normal.  If a suit of armor  is  cursed,  its
-armor  protection will be lower, and you will not be able to
-remove it.  However, not all armor with a protection that is
-lower than normal is cursed.
-
-     The  commands  to  use  weapons  are "W" (wear) and "T"
-(take off).

-
-7.3.  Scrolls
-
-     Scrolls come with titles in an unknown tongue3.   After
-you  read  a scroll, it disappears from your pack.  The com-
-mand to use a scroll is "r" (read).
-
-7.4.  Potions
-
-     Potions are labeled by the color of the  liquid  inside
-the flask.  They disappear after being quaffed.  The command
-to use a scroll is "q" (quaff).
-
-7.5.  Staves and Wands
-
-     Staves and wands do the same kinds of  things.   Staves
-are  identified  by a type of wood; wands by a type of metal
-or bone.  They are generally things you want to do to  some-
-thing  over  a long distance, so you must point them at what
-you wish to  affect  to  use  them.   Some  staves  are  not
-affected  by the direction they are pointed, though.  Staves
-come with multiple magic charges, the number  being  random,
-and when they are used up, the staff is just a piece of wood
-or metal.
-
-     The command to use a wand or staff is "z" (zap)
-
-7.6.  Rings
-
-     Rings are very useful items, since they are  relatively
-permanent  magic,  unlike  the  usually  fleeting effects of
-potions, scrolls, and staves.  Of course, the bad rings  are
-also  more  powerful.   Most  rings also cause you to use up
-food more rapidly, the rate varying with the type  of  ring.
-Rings  are differentiated by their stone settings.  The com-
-mands to use rings are "P" (put on) and "R" (remove).
-
-7.7.  Food
-
-     Food is necessary to keep you going.   If  you  go  too
-long  without  eating  you will faint, and eventually die of
-starvation.  The command to use food is "e" (eat).
-
-8.  Options
-
-     Due to variations in personal tastes and conceptions of
-the  way  rogue should do things, there are a set of options
-you can set that cause rogue to behave in various  different

-
-
-ways.
-
-8.1.  Setting the options
-
-     There  are  two  ways to set the options.  The first is
-with the "o" command  of  rogue;  the  second  is  with  the
-"ROGUEOPTS" environment variable4.
-
-8.1.1.  Using the `o' command
-
-     When you type "o" in rogue, it clears  the  screen  and
-displays  the current settings for all the options.  It then
-places the cursor by the value of the first option and waits
-for  you to type.  You can type a <RETURN> which means to go
-to the next option, a "-" which means to go to the  previous
-option,  an  <ESCAPE>  which means to return to the game, or
-you can give the option a value.  For boolean  options  this
-merely  involves  typing "t" for true or "f" for false.  For
-string options, type the new value followed by a <RETURN>.
-
-8.1.2.  Using the ROGUEOPTS variable
-
-     The ROGUEOPTS variable is a string containing  a  comma
-separated  list  of  initial values for the various options.
-Boolean variables can be turned on by listing their name  or
-turned  off by putting a "no" in front of the name.  Thus to
-set up an environment variable so that jump is on, terse  is
-off, and the name is set to "Blue Meanie", use the command
-   % setenv ROGUEOPTS "jump,noterse,name=Blue Meanie"5
-
-8.2.  Option list
-
-     Here is a list of the options  and  an  explanation  of
-what  each  one  is  for.   The  default  value  for each is
-enclosed in square brackets.  For character string  options,
-input over fifty characters will be ignored.
-
-terse [noterse]
-     Useful for those who are tired of the sometimes lengthy
-     messages of rogue.  This is a useful option for playing
-     on  slow terminals, so this option defaults to terse if
-     you are on a slow (1200 baud or under) terminal.
-
-
-____________________
-   4  On  Version  6  systems, there is no equivalent of the
-ROGUEOPTS feature.
-   5  For  those of you who use the Bourne shell sh (1), the
-commands would be
-   $ ROGUEOPTS="jump,noterse,name=Blue Meanie"
-   $ export ROGUEOPTS

-
-
-jump [nojump]
-     If this option is set, running moves will not  be  dis-
-     played until you reach the end of the move.  This saves
-     considerable  cpu  and  display  time.    This   option
-     defaults to jump if you are using a slow terminal.
-
-flush [noflush]
-     All  typeahead  is thrown away after each round of bat-
-     tle.  This is useful for those who type far  ahead  and
-     then watch in dismay as a Bat kills them.
-
-seefloor [seefloor]
-     Display  the floor around you on the screen as you move
-     through dark rooms.  Due to the  amount  of  characters
-     generated,  this  option  defaults to noseefloor if you
-     are using a slow terminal.
-
-passgo [nopassgo]
-     Follow turnings in passageways.  If you run in  a  pas-
-     sage  and  you run into stone or a wall, rogue will see
-     if it can turn to the right or left.  If  it  can  only
-     turn  one  way,  it will turn that way.  If it can turn
-     either or neither, it will stop.   This  algorithm  can
-     sometimes  lead to slightly confusing occurrences which
-     is why it defaults to nopassgo.
-
-tombstone [tombstone]
-     Print out the tombstone at the end if you  get  killed.
-     This  is  nice  but slow, so you can turn it off if you
-     like.
-
-inven [overwrite]
-     Inventory type.  This can have  one  of  three  values:
-     overwrite,  slow,  or  clear.   With  overwrite the top
-     lines of the map are overwritten  with  the  list  when
-     inventory  is requested or when "Which item do you wish
-     to . . .? " questions are answered with  a  "*".   How-
-     ever,  if  the  list  is  longer  than a screenful, the
-     screen is cleared.  With slow, lists are displayed  one
-     item  at  a  time  on  the  top of the screen, and with
-     clear, the screen is cleared, the  list  is  displayed,
-     and  then  the  dungeon  level is re-displayed.  Due to
-     speed considerations, clear is the default  for  termi-
-     nals without clear-to-end-of-line capabilities.
-
-name [account name]
-     This  is the name of your character.  It is used if you
-     get on the top ten scorer's list.
-
-fruit [slime-mold]
-     This should hold the name of a  fruit  that  you  enjoy
-     eating.  It is basically a whimsey that rogue uses in a
-     couple of places.

-
-
-file [~/rogue.save]
-     The default file name for saving  the  game.   If  your
-     phone  is hung up by accident, rogue will automatically
-     save the game in this file.  The file  name  may  start
-     with the special character "~" which expands to be your
-     home directory.
-
-9.  Scoring
-
-     Rogue usually maintains a list of the top scoring  peo-
-ple  or  scores on your machine.  Depending on how it is set
-up, it can post either the top scores or  the  top  players.
-In  the  latter  case,  each account on the machine can post
-only one non-winning score  on  this  list.   If  you  score
-higher than someone else on this list, or better your previ-
-ous score on the list, you will be inserted  in  the  proper
-place under your current name.  How many scores are kept can
-also be set up by whoever installs it on your machine.
-
-     If you quit the game, you get out with all of your gold
-intact.   If,  however,  you  get  killed in the Dungeons of
-Doom, your body is forwarded to your next-of-kin, along with
-90%  of  your  gold; ten percent of your gold is kept by the
-Dungeons'  wizard  as a fee6.  This should make you consider
-whether you want to take one last hit at  that  monster  and
-possibly live, or quit and thus stop with whatever you have.
-If you quit, you do get all your gold, but if you swing  and
-live, you might find more.
-
-     If  you  just  want  to  see what the current top play-
-ers/games list is, you can type
-          % @PROGRAM@ -s

-10.  Acknowledgements
-
-     Rogue was originally conceived of by Glenn Wichman  and
-Michael  Toy.   Ken Arnold and Michael Toy then smoothed out
-the user interface, and added jillions of new features.   We
-would  like  to  thank  Bob  Arnold,  Michelle  Busch,  Andy
-Hatcher, Kipp Hickman, Mark Horton, Daniel Jensen, Bill Joy,
-Joe  Kalash,  Steve  Maurer,  Marty  McNary, Jan Miller, and
-Scott Nelson for their ideas and assistance;  and  also  the
-teeming  multitudes who graciously ignored work, school, and
-social life to play rogue and send us bugs, complaints, sug-
-gestions, and just plain flames.  And also Mom.

-.sh 1 Introduction
-.pp
-You have just finished your years as a student at the local fighter's guild.
-After much practice and sweat you have finally completed your training
-and are ready to embark upon a perilous adventure.
-As a test of your skills,
-the local guildmasters have sent you into the Dungeons of Doom.
-Your task is to return with the Amulet of Yendor.
-Your reward for the completion of this task
-will be a full membership in the local guild.
-In addition,
-you are allowed to keep all the loot you bring back from the dungeons.
-.pp
-In preparation for your journey,
-you are given an enchanted mace,
-a bow, and a quiver of arrows
-taken from a dragon's hoard in the far off Dark Mountains.
-You are also outfitted with elf-crafted armor
-and given enough food to reach the dungeons.
-You say goodbye to family and friends for what may be the last time
-and head up the road.
-.pp
-You set out on your way to the dungeons
-and after several days of uneventful travel,
-you see the ancient ruins
-that mark the entrance to the Dungeons of Doom.
-It is late at night,
-so you make camp at the entrance
-and spend the night sleeping under the open skies.
-In the morning you gather your weapons,
-put on your armor,
-eat what is almost your last food,
-and enter the dungeons.
-.sh 1 "What is going on here?"
-.pp
-You have just begun a game of rogue.
-Your goal is to grab as much treasure as you can,
-find the Amulet of Yendor,
-and get out of the Dungeons of Doom alive.
-On the screen,
-a map of where you have been
-and what you have seen on the current dungeon level is kept.
-As you explore more of the level,
-it appears on the screen in front of you.
-.pp
-Rogue differs from most computer fantasy games in that it is screen oriented.
-Commands are all one or two keystrokes\**
-.(f
-\** As opposed to pseudo English sentences.
-.)f
-and the results of your commands
-are displayed graphically on the screen rather
-than being explained in words.\**
-.(f
-\** A minimum screen size of 24 lines by 80 columns is required.
-If the screen is larger, only the 24x80 section will be used
-for the map.
-.)f
-.pp
-Another major difference between rogue and other computer fantasy games
-is that once you have solved all the puzzles in a standard fantasy game,
-it has lost most of its excitement and it ceases to be fun.
-Rogue,
-on the other hand,
-generates a new dungeon every time you play it
-and even the author finds it an entertaining and exciting game.
-.sh 1 "What do all those things on the screen mean?"
-.pp
-In order to understand what is going on in rogue
-you have to first get some grasp of what rogue is doing with the screen.
-The rogue screen is intended
-to replace the \*(lqYou can see ...\*(rq descriptions
-of standard fantasy games.
-Figure 1 is a sample of what a rogue screen might look like.

-.sh 2 "The bottom line"
-.pp
-At the bottom line of the screen
-are a few pieces of cryptic information
-describing your current status.
-Here is an explanation of what these things mean:
-.ip Level \w'Level\ \ 'u
-This number indicates how deep you have gone in the dungeon.
-It starts at one and goes up as you go deeper into the dungeon.
-.ip Gold \w'Level\ \ 'u
-The number of gold pieces you have managed to find
-and keep with you so far.
-.ip Hp \w'Level\ \ 'u
-Your current and maximum health points.
-Health points indicate how much damage you can take before you die.
-The more you get hit in a fight,
-the lower they get.
-You can regain health points by resting.
-The number in parentheses
-is the maximum number your health points can reach.
-.ip Str \w'Level\ \ 'u
-Your current strength and maximum ever strength.
-This can be any integer less than or equal to 31,
-or greater than or equal to three.
-The higher the number,
-the stronger you are.
-The number in the parentheses
-is the maximum strength you have attained so far this game.
-.ip Arm \w'Level\ \ 'u
-Your current armor protection.
-This number indicates how effective your armor is
-in stopping blows from unfriendly creatures.
-The higher this number is,
-the more effective the armor.
-.ip Exp \w'Level\ \ 'u
-These two numbers give your current experience level
-and experience points.
-As you do things,
-you gain experience points.
-At certain experience point totals,
-you gain an experience level.
-The more experienced you are,
-the better you are able to fight and to withstand magical attacks.
-.sh 2 "The top line"
-.pp
-The top line of the screen is reserved
-for printing messages that describe things
-that are impossible to represent visually.
-If you see a \*(lq--More--\*(rq on the top line,
-this means that rogue wants to print another message on the screen,
-but it wants to make certain
-that you have read the one that is there first.
-To read the next message,
-just type a space.
-.sh 2 "The rest of the screen"
-.pp
-The rest of the screen is the map of the level
-as you have explored it so far.
-Each symbol on the screen represents something.
-Here is a list of what the various symbols mean:
-.ip @
-This symbol represents you, the adventurer.
-.ip "-\^|"
-These symbols represent the walls of rooms.
-.ip +
-A door to/from a room.
-.ip .
-The floor of a room.
-.ip #
-The floor of a passage between rooms.
-.ip *
-A pile or pot of gold.
-.ip )
-A weapon of some sort.
-.ip ]
-A piece of armor.
-.ip !
-A flask containing a magic potion.
-.ip ?
-A piece of paper, usually a magic scroll.
-.ip =
-A ring with magic properties
-.ip /
-A magical staff or wand
-.ip ^
-A trap, watch out for these.
-.ip %
-A staircase to other levels
-.ip :
-A piece of food.
-.ip A-Z
-The uppercase letters
-represent the various inhabitants of the Dungeons of Doom.
-Watch out, they can be nasty and vicious.
-.sh 1 Commands
-.pp
-Commands are given to rogue by typing one or two characters.
-Most commands can be preceded by a count to repeat them
-(e.g. typing 
-.Cs 10s
-will do ten searches).
-Commands for which counts make no sense
-have the count ignored.
-To cancel a count or a prefix,
-type \*E.
-The list of commands is rather long,
-but it can be read at any time during the game with the
-.Cs ?
-command.
-Here it is for reference,
-with a short explanation of each command.
-.ip ?
-The help command.
-Asks for a character to give help on.
-If you type a
-.Cs * ,
-it will list all the commands,
-otherwise it will explain what the character you typed does.
-.ip /
-This is the \*(lqWhat is that on the screen?\*(rq command.
-A
-.Cs /
-followed by any character that you see on the level,
-will tell you what that character is.
-For instance,
-typing
-.Cs /@
-will tell you that the
-.Cs @
-symbol represents you, the player.
-.ip "h, H, ^H"
-Move left.
-You move one space to the left.
-If you use upper case
-.Cs h ,
-you will continue to move left until you run into something.
-This works for all movement commands
-(e.g.
-.Cs L
-means run in direction 
-.Cs l )
-If you use the \*(lqcontrol\*(rq
-.Cs h ,
-you will continue moving in the specified direction
-until you pass something interesting or run into a wall.
-You should experiment with this,
-since it is a very useful command,
-but very difficult to describe.
-This also works for all movement commands.
-.ip j
-Move down.
-.ip k
-Move up.
-.ip l
-Move right.
-.ip y
-Move diagonally up and left.
-.ip u
-Move diagonally up and right.
-.ip b
-Move diagonally down and left.
-.ip n
-Move diagonally down and right.
-.ip t
-Throw an object.
-This is a prefix command.
-When followed with a direction
-it throws an object in the specified direction.
-(e.g. type
-.Cs th
-to throw
-something to the left.)
-.ip f
-Fight until someone dies.
-When followed with a direction
-this will force you to fight the creature in that direction
-until either you or it bites the big one.
-.ip m
-Move onto something without picking it up.
-This will move you one space in the direction you specify and,
-if there is an object there you can pick up,
-it won't do it.
-.ip z
-Zap prefix.
-Point a staff or wand in a given direction
-and fire it.
-Even non-directional staves must be pointed in some direction
-to be used.
-.ip ^
-Identify trap command.
-If a trap is on your map
-and you can't remember what type it is,
-you can get rogue to remind you
-by getting next to it and typing
-.Cs ^
-followed by the direction that would move you on top of it.
-.ip s
-Search for traps and secret doors.
-Examine each space immediately adjacent to you
-for the existence of a trap or secret door.
-There is a large chance that even if there is something there,
-you won't find it,
-so you might have to search a while before you find something.
-.ip >
-Climb down a staircase to the next level.
-Not surprisingly, this can only be done if you are standing on staircase.
-.ip <
-Climb up a staircase to the level above.
-This can't be done without the Amulet of Yendor in your possession.
-.ip "."
-Rest.
-This is the \*(lqdo nothing\*(rq command.
-This is good for waiting and healing.
-.ip ,
-Pick up something.
-This picks up whatever you are currently standing on,
-if you are standing on anything at all.
-.ip i
-Inventory.
-List what you are carrying in your pack.
-.ip I
-Selective inventory.
-Tells you what a single item in your pack is.
-.ip q
-Quaff one of the potions you are carrying.
-.ip r
-Read one of the scrolls in your pack.
-.ip e
-Eat food from your pack.
-.ip w
-Wield a weapon.
-Take a weapon out of your pack and carry it for use in combat,
-replacing the one you are currently using (if any).
-.ip W
-Wear armor.
-You can only wear one suit of armor at a time.
-This takes extra time.
-.ip T
-Take armor off.
-You can't remove armor that is cursed.
-This takes extra time.
-.ip P
-Put on a ring.
-You can wear only two rings at a time
-(one on each hand).
-If you aren't wearing any rings,
-this command will ask you which hand you want to wear it on,
-otherwise, it will place it on the unused hand.
-The program assumes that you wield your sword in your right hand.
-.ip R
-Remove a ring.
-If you are only wearing one ring,
-this command takes it off.
-If you are wearing two,
-it will ask you which one you wish to remove,
-.ip d
-Drop an object.
-Take something out of your pack and leave it lying on the floor.
-Only one object can occupy each space.
-You cannot drop a cursed object at all
-if you are wielding or wearing it.
-.ip c
-Call an object something.
-If you have a type of object in your pack
-which you wish to remember something about,
-you can use the call command to give a name to that type of object.
-This is usually used when you figure out what a
-potion, scroll, ring, or staff is
-after you pick it up,
-or when you want to remember
-which of those swords in your pack you were wielding.
-.ip D
-Print out which things you've discovered something about.
-This command will ask you what type of thing you are interested in.
-If you type the character for a given type of object
-(\fIe.g.\fP
-.Cs !
-for potion)
-it will tell you which kinds of that type of object you've discovered
-(\fIi.e.\fP, figured out what they are).
-This command works for potions, scrolls, rings, and staves and wands.
-.ip o
-Examine and set options.
-This command is further explained in the section on options.
-.ip ^R
-Redraws the screen.
-Useful if spurious messages or transmission errors
-have messed up the display.
-.ip ^P
-Print last message.
-Useful when a message disappears before you can read it.
-This only repeats the last message
-that was not a mistyped command
-so that you don't loose anything by accidentally typing
-the wrong character instead of ^P.
-.ip \*E
-Cancel a command, prefix, or count.
-.ip !
-Escape to a shell for some commands.
-.ip Q
-Quit.
-Leave the game.
-.ip S
-Save the current game in a file.
-It will ask you whether you wish to use the default save file.
-.i Caveat :
-Rogue won't let you start up a copy of a saved game,
-and it removes the save file as soon as you start up a restored game.
-This is to prevent people from saving a game just before a dangerous position
-and then restarting it if they die.
-To restore a saved game,
-give the file name as an argument to rogue.
-As in
-.ti +1i
-.nf
-% rogue \fIsave\*_file\fP
-.ip
-To restart from the default save file (see below),
-run
-.ti +1i
-.nf
-% rogue \-r
-.ip v
-Prints the program version number.
-.ip )
-Print the weapon you are currently wielding
-.ip ]
-Print the armor you are currently wearing
-.ip =
-Print the rings you are currently wearing
-.ip @
-Reprint the status line on the message line
-.sh 1 Rooms
-.pp
-Rooms in the dungeons are either lit or dark.
-If you walk into a lit room,
-the entire room will be drawn on the screen as soon as you enter.
-If you walk into a dark room,
-it will only be displayed as you explore it.
-Upon leaving a room,
-all monsters inside the room
-are erased from the screen.
-In the darkness you can only see one space
-in all directions around you.
-A corridor is always dark.
-.sh 1 Fighting
-.pp
-If you see a monster and you wish to fight it,
-just attempt to run into it.
-Many times a monster you find will mind its own business
-unless you attack it.
-It is often the case that discretion is the better part of valor.
-.sh 1 "Objects you can find"
-.pp
-When you find something in the dungeon,
-it is common to want to pick the object up.
-This is accomplished in rogue by walking over the object
-(unless you use the
-.Cs m
-prefix, see above).
-If you are carrying too many things,
-the program will tell you and it won't pick up the object,
-otherwise it will add it to your pack
-and tell you what you just picked up.
-.pp
-Many of the commands that operate on objects must prompt you
-to find out which object you want to use.
-If you change your mind and don't want to do that command after all,
-just type an \*E and the command will be aborted.
-.pp
-Some objects, like armor and weapons,
-are easily differentiated.
-Others, like scrolls and potions,
-are given labels which vary according to type.
-During a game,
-any two of the same kind of object
-with the same label
-are the same type.
-However,
-the labels will vary from game to game.
-.pp
-When you use one of these labeled objects,
-if its effect is obvious,
-rogue will remember what it is for you.
-If it's effect isn't extremely obvious
-you will be asked what you want to scribble on it
-so you will recognize it later,
-or you can use the
-.Cs call
-command
-(see above).
-.sh 2 Weapons
-.pp
-Some weapons,
-like arrows,
-come in bunches,
-but most come one at a time.
-In order to use a weapon,
-you must wield it.
-To fire an arrow out of a bow,
-you must first wield the bow,
-then throw the arrow.
-You can only wield one weapon at a time,
-but you can't change weapons if the one
-you are currently wielding is cursed.
-The commands to use weapons are
-.Cs w
-(wield)
-and
-.Cs t
-(throw).
-.sh 2 Armor
-.pp
-There are various sorts of armor lying around in the dungeon.
-Some of it is enchanted,
-some is cursed,
-and some is just normal.
-Different armor types have different armor protection.
-The higher the armor protection,
-the more protection the armor affords against the blows of monsters.
-Here is a list of the various armor types and their normal armor protection:
-.(b
-.TS
-box center;
-l r.
-\ \ \fIType	Protection\fP
-None	0
-Leather armor	2
-Studded leather / Ring mail	3
-Scale mail	4
-Chain mail	5
-Banded mail / Splint mail	6
-Plate mail	7
-.TE
-.)b
-.lp
-If a piece of armor is enchanted,
-its armor protection will be higher than normal.
-If a suit of armor is cursed,
-its armor protection will be lower,
-and you will not be able to remove it.
-However, not all armor with a protection that is lower than normal is cursed.
-.pp
-The commands to use weapons are
-.Cs W
-(wear)
-and
-.Cs T
-(take off).
-.sh 2 Scrolls
-.pp
-Scrolls come with titles in an unknown tongue\**.
-.(f
-\** Actually, it's a dialect spoken only by the twenty-seven members
-of a tribe in Outer Mongolia,
-but you're not supposed to
-.i know
-that.
-.)f
-After you read a scroll,
-it disappears from your pack.
-The command to use a scroll is
-.Cs r
-(read).
-.sh 2 Potions
-.pp
-Potions are labeled by the color of the liquid inside the flask.
-They disappear after being quaffed.
-The command to use a scroll is
-.Cs q
-(quaff).
-.sh 2 "Staves and Wands"
-.pp
-Staves and wands do the same kinds of things.
-Staves are identified by a type of wood;
-wands by a type of metal or bone.
-They are generally things you want to do to something
-over a long distance,
-so you must point them at what you wish to affect
-to use them.
-Some staves are not affected by the direction they are pointed, though.
-Staves come with multiple magic charges,
-the number being random,
-and when they are used up,
-the staff is just a piece of wood or metal.
-.pp
-The command to use a wand or staff is
-.Cs z
-(zap)
-.sh 2 Rings
-.pp
-Rings are very useful items,
-since they are relatively permanent magic,
-unlike the usually fleeting effects of potions, scrolls, and staves.
-Of course,
-the bad rings are also more powerful.
-Most rings also cause you to use up food more rapidly,
-the rate varying with the type of ring.
-Rings are differentiated by their stone settings.
-The commands to use rings are
-.Cs P
-(put on)
-and
-.Cs R
-(remove).
-.sh 2 Food
-.pp
-Food is necessary to keep you going.
-If you go too long without eating you will faint,
-and eventually die of starvation.
-The command to use food is
-.Cs e
-(eat).
-.sh 1 Options
-.pp
-Due to variations in personal tastes
-and conceptions of the way rogue should do things,
-there are a set of options you can set
-that cause rogue to behave in various different ways.
-.sh 2 "Setting the options"
-.pp
-There are two ways to set the options.
-The first is with the
-.Cs o
-command of rogue;
-the second is with the
-.Cs ROGUEOPTS
-environment variable\**.
-.(f
-\** On Version 6 systems,
-there is no equivalent of the ROGUEOPTS feature.
-.br
-.)f
-.br
-.sh 3 "Using the `o' command"
-.pp
-When you type
-.Cs o
-in rogue,
-it clears the screen
-and displays the current settings for all the options.
-It then places the cursor by the value of the first option
-and waits for you to type.
-You can type a \*R
-which means to go to the next option,
-a
-.Cs \-
-which means to go to the previous option,
-an \*E
-which means to return to the game,
-or you can give the option a value.
-For boolean options this merely involves typing
-.Cs t
-for true or
-.Cs f
-for false.
-For string options,
-type the new value followed by a \*R.
-.sh 3 "Using the ROGUEOPTS variable"
-.pp
-The ROGUEOPTS variable is a string
-containing a comma separated list of initial values
-for the various options.
-Boolean variables can be turned on by listing their name
-or turned off by putting a
-.Cs no
-in front of the name.
-Thus to set up an environment variable so that
-.b jump
-is on,
-.b terse
-is off,
-and the
-.b name
-is set to \*(lqBlue Meanie\*(rq,
-use the command
-.nf
-.ti +3n
-% setenv ROGUEOPTS "jump,noterse,name=Blue Meanie"\**
-.fi
-.(f
-\**
-For those of you who use the Bourne shell sh (1), the commands would be
-.in +3
-.nf
-$ ROGUEOPTS="jump,noterse,name=Blue Meanie"
-$ export ROGUEOPTS
-.fi
-.in +0
-.)f
-.sh 2 "Option list"
-.pp
-Here is a list of the options
-and an explanation of what each one is for.
-The default value for each is enclosed in square brackets.
-For character string options,
-input over fifty characters will be ignored.
-.ip "\fBterse\fP [\fI\^noterse\^\fP]"
-Useful for those who are tired of the sometimes lengthy messages of rogue.
-This is a useful option for playing on slow terminals,
-so this option defaults to
-.i terse
-if you
-are on a slow (1200 baud or under) terminal.
-.ip "\fBjump\fP [\fI\^nojump\^\fP]"
-If this option is set,
-running moves will not be displayed
-until you reach the end of the move.
-This saves considerable cpu and display time.
-This option defaults to
-.i jump
-if you are using a slow terminal.
-.ip "\fBflush\fP [\fI\^noflush\^\fP]"
-All typeahead is thrown away after each round of battle.
-This is useful for those who type far ahead
-and then watch in dismay as a Bat kills them.
-.ip "\fBseefloor\fP [\fI\^seefloor\^\fP]"
-Display the floor around you on the screen
-as you move through dark rooms.
-Due to the amount of characters generated,
-this option defaults to
-.i noseefloor
-if you are using a slow terminal.
-.ip "\fBpassgo\fP [\fI\^nopassgo\^\fP]"
-Follow turnings in passageways.
-If you run in a passage
-and you run into stone or a wall,
-rogue will see if it can turn to the right or left.
-If it can only turn one way,
-it will turn that way.
-If it can turn either or neither,
-it will stop.
-This algorithm can sometimes lead to slightly confusing occurrences
-which is why it defaults to \fInopassgo\fP.
-.ip "\fBtombstone\fP [\fI\^tombstone\^\fP]"
-Print out the tombstone at the end if you get killed.
-This is nice but slow, so you can turn it off if you like.
-.ip "\fBinven\fP [\fI\^overwrite\^\fP]"
-Inventory type.
-This can have one of three values:
-.i overwrite ,
-.i slow ,
-or
-.i clear .
-With
-.i overwrite
-the top lines of the map are overwritten
-with the list
-when inventory is requested
-or when
-\*(lqWhich item do you wish to \fB. . .\fP? \*(rq questions
-are answered with a
-.Cs * .
-However, if the list is longer than a screenful,
-the screen is cleared.
-With
-.i slow ,
-lists are displayed one item at a time on the top of the screen,
-and with
-.i clear ,
-the screen is cleared,
-the list is displayed,
-and then the dungeon level is re-displayed.
-Due to speed considerations,
-.i clear
-is the default for terminals without
-clear-to-end-of-line capabilities.
-.ip "\fBname\fP [account name]"
-This is the name of your character.
-It is used if you get on the top ten scorer's list.
-.ip "\fBfruit\fP [\fI\^slime-mold\^\fP]"
-This should hold the name of a fruit that you enjoy eating.
-It is basically a whimsey that rogue uses in a couple of places.
-.ip "\fBfile\fP [\fI\^~/rogue.save\^\fP]"
-The default file name for saving the game.
-If your phone is hung up by accident,
-rogue will automatically save the game in this file.
-The file name may start with the special character
-.Cs ~
-which expands to be your home directory.
-.sh 1 Scoring
-.pp
-Rogue usually maintains a list
-of the top scoring people or scores on your machine.
-Depending on how it is set up,
-it can post either the top scores
-or the top players.
-In the latter case,
-each account on the machine
-can post only one non-winning score on this list.
-If you score higher than someone else on this list,
-or better your previous score on the list,
-you will be inserted in the proper place
-under your current name.
-How many scores are kept
-can also be set up by whoever installs it on your machine.
-.pp
-If you quit the game, you get out with all of your gold intact.
-If, however, you get killed in the Dungeons of Doom,
-your body is forwarded to your next-of-kin,
-along with 90% of your gold;
-ten percent of your gold is kept by the Dungeons' wizard as a fee\**.
-.(f
-\** The Dungeon's wizard is named Wally the Wonder Badger.
-Invocations should be accompanied by a sizable donation.
-.)f
-This should make you consider whether you want to take one last hit
-at that monster and possibly live,
-or quit and thus stop with whatever you have.
-If you quit, you do get all your gold,
-but if you swing and live, you might find more.
-.pp
-If you just want to see what the current top players/games list is,
-you can type
-.ti +1i
-.nf
-% @PROGRAM@ \-s
-.br
-.sh 1 Acknowledgements
