[Web-cyradm] Is there any 'user' documentation?

[cl at isbd.net]

I know this sounds a silly question (and I've been using web-cyradm
for quite a while now) but is there any 'user' documentation for
web-cyradm?

E.g. where can I find out what formats of E-Mail address I can use
when I edit an account.

I know I can specify a 'catch-all' by putting nothing before the @,
however I would now like to know if I can specify an address like:-
    *chris*@some.domain
to catch all addresses that have 'chris' somewhere in them.

The web-cyradm.org web site seems to have only (but good) installation
documentation.
