Psfig allows the inclusion of compressed PostScriptfiles when using
the dvips dvi processor.
The shell script pscompress is used to compress figures, and
produces two files: filename.bb and filename.Z.
The first file contains the bounding box comment only, while the second
file contains the actual compressed PostScript file. Usage:
% pscompress filename
When psfig searches for a figure, if it fails to find
filename, it then searches for filename.bb.
If that file exists, it is used for bounding box processing,
and a command to decompress and include the file filename.Z
is issued to dvips.
