@#!/bin/sh
# Script to convert an arbitrary PostScript image to an encapsulated
# PostScript image with a bitmap, suitable for incorporation into
# FrameMaker, LaTeX, troff, etc.
#
# Options:
#	-gs	Use ghostscript to convert to EPSI
#	-news	Use Sun's X/NeWS (OpenWindows) to convert to EPSI
#	-strip	Strip all %% directives from the source file -- useful
#		when dealing with Adobe Illustrator and others who
#		use directives incompatible with this coversion.
#	-2x	Use 2x resolution
#	-noprev	Do not include the preview bitmap
#
# Note in the USAGE line below, the source PostScript file must end
# in a .ps extention.  This is a GhostScript requirement, not mine...
#
# I am providing this without any guarantee.
#
# Thu Nov 29 10:57:05 EST 1990 - Doug Crabill dgc@@cs.purdue.edu
#	Original release.
#
# Sun Jan 11 02:47:26 EST 1998 - William C. Cheng <bill.cheng@@acm.org>
#	Handles Aladdin Ghostscript 5.x (no pstoppm.ps).
# Thu May 20 11:29:12 EDT 1999 - William C. Cheng <bill.cheng@@acm.org>
#	Handles the "-2x" command line argument (needs netpbm-20may1999).
# Fri Sep  1 14:32:15 EDT 2000 - William C. Cheng <bill.cheng@@acm.org>
#	Make the default STYLE to be "ppm".
# Fri Mar 23 11:18:17 PST 2001 - William C. Cheng <bill.cheng@@acm.org>
#	Handles the "-noprev" command line argument.
