Synopsis:
$mask(<type> <address>)
Technical:
This function returns <address> in a wildcard mask according to the type
specified by <type>. The mask types are defined in the following table:
<type> <address> has a hostname <address> has an ip
-------------------------------------------------------------------
0 *!u@h.d *!u@d.h
1 *!*u@h.d *!*u@d.h
2 *!*@h.d *!*@d.h
3 *!*u@*.d *!*u@d.*
4 *!*@*.d *!*@d.*
5 n!u@h.d n!u@d.h
6 n!*u@h.d n!*u@d.h
7 n!*@h.d n!*@d.h
8 n!*u@*.d n!*u@d.*
9 n!*@*.d n!*@d.*
10 *!*@h.d *!*@d.*
11 *!*u@h.d *!*u@d.*
12 n!*@h.d n!*@d.*
13 n!*u@h.d n!*u@d.*
where n=nick, u=user, h=host, and d=domain
With the following modifications: In the ``local'' portion of
the hostname, all sequence of numbers are substituted with a
single '*'. In the username, leading ~'s are also substituted
with a single '*'.
Returns:
<address> in a wildcard mask according to <type>
Examples:
$mask(3 foo!bar@long.host.blah.com)
returns:
*!*bar@*.blah.com
$mask(10 nick!user@ppp-147-0-52-129.frobitz.com)
returns:
*!*@ppp-*-*-*-*.frobitz.com

Other Notes:
This function strips all tildes ('~') from the left of the username. For
script writers, this means that in mask types 0 and 5, the function is
*NOT* guaranteed to produce a mask matching the given address. If a script
is to use these types, they should expect tildes to be stripped and be able
to act accordingly.
