Ghostscript PostScript "distiller"
ps2ps [ options ] input output.ps
eps2eps [ options ] input output.eps
ps2ps uses gs(1) to convert PostScript(tm) or PDF(tm) file "input" to simpler, normalized and (usually) faster PostScript in "output.ps". The output is level 2 DSC 3.0 conforming PostScript.
eps2eps performs the equivalent optimization, creating Encapsulated PostScript (EPS) files. NB, despite the name, the input need not be an EPS file, PostScript or indeed PDF files are equally acceptable.
Both accept any general Ghostscript command line options, and options specific to the ps2write and eps2write devices.
Run "gs -h" to find the location of Ghostscript documentation on your system, from which you can get more details.
