#
# >>Purpose::
# {{CMD:prn2ps}} converts Windows PostScript to Unix PostScript.
# The input to this program is typically generated by printing
# to a PostScript printer connected to the FILE: logical device.
# The output can be converted to Encapsulated PostScript using
# GhostScript's {{CMD:p2epsi}} program.
#
# >>Description::
# !SDF_OPT_STD
#
# For each input file, the output is generated by:
#
# * deleting the {{PageSize}} information
# * deleting the control-D at the end of the file.
#
# >>Limitations::
# If {{CMD:ps2epsi}} doesn't like the output, you may need to
# use another printer driver to generate the input.
# On Windows NT 4.0, the {{Canon PS-IPU Color Laser Copier v52.3}}
# driver works most of the time.
#
# >>Examples::
# To generate an Encapsulated PostScript file from Windows PostScript:
#
# >  prn2ps -ops myfig.prn
# >  ps2epsi myfig.ps
#
# >>Implementation::
#
