The Mikribot User's Manual - The !userinfo Command
Usage: !userinfo [-email|-mask] <mask> [all]
Userlevel required: 50
Purpose: !userinfo searches for a nick and email entries in the
userlist. If only a mask is given, !userinfo searches the
userlist until it finds an entry with a matching nick field.
If -the email option is used, !userinfo matches the email field.
If the -mask option is used, !userinfo matches the usermask and
returns the mask, nick, and email fields. If the "all" option is
used, ALL matching entries are listed, not just the first one.
