-### STEP 0 :: Verify that we have the necessary requirements.
-###
-### This script requires recent versions of Perl, OpenSSL and PPPD (including
-### the 'chat' program), and that they all be in our PATH.  This script was
-### written and tested with the following versions:
-###	FirePass:	5.5 and 6.0
-###	Perl:		5.8.8
-###	OpenSSL:	0.9.8b
-###	PPPD:		2.4.4
-
-###
-### STEP 1 :: Set up variables with the proper information to log in.
-###
-
-# Default values for the FQDN or IP of the FirePass we wish to connect to, the
-# name of our Network Access favorite, and our username/pasword.  All of these
-# can be passed as arguments, if desired.

-=head1 SYNOPSIS
-
- vpn [-d|--debug] [-H|--host <host>] [-o|--opt <ppp option>]...
-     [-s|--script <script>]
-     [-u|--user <user>] [-p|--passcode <passcode>]
-
- vpn [-h|--help]
- vpn [-m|--man]
-
-=head1 DESCRIPTION
-
-Ths script establishes a VPN connecttion to a FirePass server.
-B<Note:> This script requires B<root> privileges and should be run via sudo
-or some other approbiate mechanism. (You may install it SUID root. This
-is the safest way, since the script rises its privileges only when
-necessary, instead of operating all the time as root.)
-
-=head1 OPTIONS
-
-=over
-
-=item B<-d>
-
-Print debug output from pppd. In this mode the script (and the pppd)
-will not detach from your terminal and the script code will not be
-executed.  (default: 0)
-
-=item B<-h>|B<--help>
-
-A short help. (defualt: off)
-
-=item B<-H>|B<--host> I<host>
-
-Host to connect to. (defaults to C<connectwdf.sap.corp>)
-
-=item B<-m>|B<--man>
-
-This man page. (default: off)
-
-=item B<-n>|B<--name> I<name>
-
-Name of the service(?). (default: to 'SAP Network Access')
-
-=item B<-o>|B<--opts> I<ppp options>
-
-Additional options for ppp. Can be specified multiple times. (default: nodetach)
-Good choices are C<detach>, or C<updetach>.
-B<Note:> The C<nodefaultroute> is set automatically.
-
-=item B<-p>|B<--passcode> I<passcode>
-
-Your passcode, if not supplied, F</dev/tty> is opened for reading
-the passcode. (no default)
-
-=item B<-s>|B<--script> I<script>
-
-Script to execute after establishing the IP link. (See the B<-d> option
-above!). (no default)
-
-B<Note:> You should consider using the F</etc/ppp/ip-up.d/> scripts.
-(see below)
-
-B<Note2:> NOT IMPLEMENTED YET!
-
-
-=item B<-u>|B<--user> I<user>
-
-Your D|C|I user, not really optional. (no default)
-
