Net::Finger - a Perl implementation of a finger client.

       Dennis Taylor, <corbeau@execpc.com>

       •   Doesn't yet do non-blocking requests. (FITNR. Really.)

       •   Doesn't do local requests unless there's a finger server running on localhost.

       •   Contrary to the name's implications, this module involves no teledildonics.

       Net::Finger is a simple, straightforward implementation of a finger client in Perl -- so simple, in fact,
       that writing this documentation is almost unnecessary.

       This module has one automatically exported function, appropriately entitled "finger()". It takes two
       arguments:

       •   A  username or email address to finger. (Yes, it does support the vaguely deprecated "user@host@host"
           syntax.) If you need to use a port other than the default finger port (79), you can specify  it  like
           so: "username@hostname:port".

       •   (Optional)  A  boolean  value for verbosity. True == verbose output. If you don't give it a value, it
           defaults to false. Actually, whether this output will differ from the non-verbose version at  all  is
           up to the finger server.

       "finger()"  is  context-sensitive. If it's used in a scalar context, it will return the server's response
       in one large string. If it's used in an array context, it will return the response as  a  list,  line  by
       line.  If  an error of some sort occurs, it returns undef and puts a string describing the error into the
       package global variable $Net::Finger::error. If  you'd  like  to  see  some  excessively  verbose  output
       describing  every  step  "finger()"  takes  while  talking  to  the other server, put a true value in the
       variable $Net::Finger::debug.

       Here's a sample program that implements a very tiny, stripped-down finger(1):

           #!/usr/bin/perl -w

           use Net::Finger;
           use Getopt::Std;
           use vars qw($opt_l);

           getopts('l');
           $x = finger($ARGV[0], $opt_l);

           if ($x) {
               print $x;
           } else {
               warn "$0: error: $Net::Finger::error\n";
           }
