/* ViewCP.c, based on shell_main.c TEMPLATE.
This program reads a <name>.p packing file, creates a <name>.ps
postscript file. It assumes the packing is computed and fixed,
adjusts for the image, and assuming -s flag is not set, pops up
a ghostview picture.
(Note: if -c flag is set, intend to send postscript output to stdout,
assuming its being piped into something, but don't know how to use it
yet, so this is disabled.)
Compile with:
cc -g -Wall -o ViewCP ViewCP.c -I$HOME/CP/include -L$HOME/CP/lib -L/usr/X11R6/lib -lCP_libs -lX11 -lm
Run with:
ViewCP [-c] <packing.p>
