ps2ps uses gs(1) to convert PostScript(tm) file
"input.ps" to simpler, normalized and (usually) faster PostScript in
"output.ps". Normally the output is allowed to use PostScript Level 2
or Level 3 constructs, but the -dLanguageLevel=1 option restricts
the output to Level 1.
eps2eps performs the equivalent optimization for Encapsulated
PostScript (EPS) files.
Both accept any general Ghostscript command line options, and
respectively options specific to the pswrite and epswrite devices.
Run "gs -h" to find the location of Ghostscript documentation on your
system, from which you can get more details.
The pswrite device used by both ps2ps and eps2eps produces much
lower level output than is desirable. Use with caution.
