# Purpose: Create an nroff format file from slacktrack's Perl POD
#          format manpage
# Author : Stuart Winter <mozes@slackware.com>

# Information about man pages: 
# http://www.fnal.gov/docs/products/ups/ReferenceManual/html/manpages.html
# which describes creating man pages in nroff format. 
# However, it's easier (IMO) to create them in POD format.
