+DON'T BE A DICK PUBLIC LICENSE
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 1. Do whatever you like with the original work, just don't be a dick.
+
+     Being a dick includes - but is not limited to - the following instances:
+
+     1a. Outright copyright infringement - Don't just copy the original
+         work/works and change the name.
+     1b. Selling the unmodified original with no work done what-so-ever,
+         that's REALLY being a dick.
+     1c. Modifying the original work to contain hidden harmful content.
+         That would make you a PROPER dick.
+
+ 2. If you become rich through modifications, related works/services, or
+    supporting the original work, share the love. Only a dick would make
+    loads off this work and not buy the original work's creator(s) a pint.
+
+ 3. Code is provided with no warranty. Using somebody else's code and
+    bitching when it goes wrong makes you a DONKEY dick. Fix the problem
+    yourself. A non-dick would submit the fix back or submit a bug report.
+
+ 4. If you use code, calling it your own would make you a ROYAL dick.
+    Alternatively, even just a comment giving attribution to where you found
+    the code would be OK.
