# 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.
#
# 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.
