There are several libraries and programs that are not necessary for basic
use of mooix, but make it work better or are needed for specific features.
If you installed mooix from a package, you may or may not get these
automatically installed.

To allow moo users to use the edit command, you need to install a
restricted editor, which can be configured to only edit one file, and does
not allow users to run external commands. Mooix by default will use rjoe,
if it is installed. Mooix also uses the pager, less so make sure you have
that installed.

Most of the optional software is perl modules from CPAN.

Recommended for best use of mooix:

Sys::Utmp		Logging hostnames of moo users. Strongly recommended.
Mail::Sendmail		New user registration.
Lingua::EN::Words2Nums	Parsing numbers. (> my second alias is "Fred")
Authen::PAM		Password changing and the in.mooix server.

Suggested extras:

Time::Duration		Pretty-printing of login duration and stuff.
Sys::CpuLoad		The load command.
Date::Manip		Parsing dates in event objects.
Time::Human		Used by some clocks for pretty time printing.
Lingua::EN::Inflect	Used by the addcommand command to properly
			inflect verbs, and by the dig command.

Note that any of the above software can be installed at any time, even
after you have installed mooix.
