# ### Installing Roundcube
# We install Roundcube from sources, rather than from Ubuntu, because:
#
# 1. Ubuntu's `roundcube-core` package has dependencies on Apache & MySQL, which we don't want.
#
# 2. The Roundcube shipped with Ubuntu is consistently out of date.
#
# 3. It's packaged incorrectly --- it seems to be missing a directory of files.
#
# So we'll use apt-get to manually install the dependencies of roundcube that we know we need,
# and then we'll manually install roundcube from source.
# These dependencies are from `apt-cache showpkg roundcube-core`.

# Install Roundcube from source if it is not already present or if it is out of date.
# Combine the Roundcube version number with the commit hash of plugins to track
# whether we have the latest version of everything.
# For the latest versions, see:

# https://github.com/mfreiholz/persistent_login/commits/master
# https://github.com/stremlau/html5_notifier/commits/master
# https://github.com/mstilkerich/rcmcarddav/releases
# The easiest way to get the package hashes is to run this script and get the hash from
# the error message.
