# rclps
# Extract text from a postscript file by executing pstotext or ps2ascii.

# The default is to use pstotext which can deal with accents, but in a
# partially broken way (it always outputs iso8859-1, when it should use utf.
#
# OTOH, ps2ascii is much faster, comes with ghostscript, and sometimes work
# better (ie: on some openoffice output files).
