Todo (for next major release):

 . .cfingerrc files for individual users.
 . userlist-only routines use password-protected keys for multi-system 
   fingers.  (Perhaps even private key stuff)
 . Update RFC1413 routine to include "<connection-refused>" if a connection 
   was refused during ident, or "<illegal-data>" if illegal data was
   received.  (Or even make these configurable!  :)
 . Add ability to handle multiple hosts in configuration.
 . Rewrite a non-pedantic type configuration reader...
 . Recursion checking in cfingerd "@" list requests.
 . Add ability to specify Mailbox instead of a defined one.
 . Check *all* occurrences of sscanf() against possible buffer overflows.
   This is a favourite problem when passing arguments to tons of routines
   for parsing and reacting.
 . Are 80 characters enough for a username?
 . Use correct CRLF for linefeeds.
 . Use autoconf
 . Error message for search should be configurable
