#Subject: MGETTY+SENDFAX's make.coverpg converted to perl - FYI
#To: gert@greenie.muc.de
#Date: Mon, 2 Jun 1997 17:35:43 -0400 (EDT)

#Hi Gert Doering,
#
#I've been playing with your fax package mgetty-1.1.6 and find
#it useful.
#
#The following program is a direct conversion of your
#shell/awk script to perl for better performance
#and easier maint. IMHO so if you want it just take it. 
#
#Sincerely,
#
#jason

# make.coverpg -- slightly advanced version, use ghostscript 
#                 (just a sample, naturally you have to adapt all the texts!) 
# 
# Author: gert@greenie.muc.de 
#
# Converted to perl by Jason Mathews <mathews@nssdc.gsfc.nasa.gov> 6/2/97
# - Keeps postscript in memory opposed to writing a temp file
# 
# Syntax: 
#       make.coverpg [-m memo string] <pages>  <sender-ID>   <sender-NAME>
#                    <receiver-ID> <receiver-NAME> <date> <time> 
 
# 
# if called with "-m <memo-file>", put that file on cover page: 
if ($ARGV[0] eq "-m") { 
    shift;
    $MEMO = shift;
}

#
# get arguments
#
$PAGES=shift;
$S_ID=shift;
$S_NAME=shift;
$R_ID=shift;
$R_NAME=shift;
$DATE=shift;
$TIME=shift;

#
# chose proper driver for resolution

$driver = $ENV{'normal_res'} ?  "dfaxlow" : "dfaxhigh";
