# OpenOffice Font Printer
#
# Every time OpenOffice runs, it looks through paths on your
# system for possible fonts.  The found fonts are stored (with
# formatting information) to the pspfontcache file in your
# home directory.
#
# This script parses the pspfontcache file and creates a very
# basic oowriter file (.sxw) that displays all of the fonts
# in a single document.
#
# See http://www.openoffice.org/FAQs/fontguide.html for
# helpful information about font handling in OO.
#
# Usage: (in Linux)
# Run from command line under your own account
# perl gen.pl
