Reads a portable bitmap as input.
Produce an encapsulated Postscript style bitmap as output. The output
is not a stand alone postscript file, it is only a preview bitmap,
which can be included in an encapsulated PostScript file.
Note that there is no epsitopbm tool - this transformation is one way.
This utility is a part of the pstoepsi tool by Doug Crabill
(dgc@cs.purdue.edu).
