# Webmail: Using roundcube

# Ubuntu's roundcube-core has dependencies on Apache & MySQL, which we don't want, so we can't
# install roundcube directly via apt-get install.
#
# Additionally, the Roundcube shipped with Ubuntu is consistently out of date.
#
# And 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'.

# We used to install Roundcube from Ubuntu, without triggering the dependencies
# on Apache and MySQL, by downloading the debs and installing them manually.
# Now that we're beyond that, get rid of those debs before installing from source.

# Install Roundcube from source if it is not already present.
