This directory contains all of the available user CSS style sheets. These options will show up in the right click context menu. In order to en-/disable the availability of options, add/remove the appropriate symbolic link in "/etc/shellinabox/options-enabled" and restart the daemon with "sudo /etc/init.d/shellinabox restart". All options are of the form "ID_Name of Option.css". Any options with identical IDs will be put into the same option group. They are mutually exclusive and only one such option can be selected at any given time. Please note that ':', ',', and ';' are all invalid characters in option names. Options that should be turned on by default have the "_" character replaced with a "+" character. In any group of mutually exclusive options, there must be exactly one option that is turned on.
