# man2ps, (c) 2004,2005,2006,2009 Toni Corvera, published under a BSD license
#
# Saves a man page as either a PostScript (PS) or as a PDF file.
#
# This script is also used as a testbed for some experiments,
# as of now only rudimentary in-file localisation is kept, in the past
# the script could also be sourced and work as a function but it led to
# unwanted pollution of the environment.
