=head1 NAME

create_nicksfile.pl - Create a valid bitlbee .nicks file

=head1 SYNOPSIS

create_nicksfile.pl [--from=FROM] [--of=OUTPUTFILE] [--debug] FILENAME

        FROM defines which application we import from.
        Note that currently the only valid value for FROM 
        is licq.

        If of is missing, we write to bitlbee.nicks.

=head1 DESCRIPTION

We run thru the
files where the contacts reside and create
a bitlbee .nicks-file from them.

=head1 DEPENDENCIES

On the perlside, we need Getopt::Long.

=head1 CAVEATS

=head1 TODO

&import_readline_... should take a filehandle as argument.

Add more import functions. If you are interested,
to do so, you need to write the following functions:

=over

=item *

import_open_<WHATEVER>(DIR,FILENAME)

=item *

import_close_<WHATEVER>()

=item *

import_readline_<WHATEVER>()

=back

and add them to the hashes

=over

=item *

%readline_funcs

=item *

%open_funcs

=item *

%close_funcs

=back

at the top of this script.
