Save the files

pst-optic.sty
pst-optic.tex

in any place, where latex or any other TeX program will find it.
If you like to get the documentation file in another format run 

latex pst-optic-doc.tex
biber pst-optic.doc
latex pst-optic-doc.tex
dvips pst-optic-doc.dvi

to get a PostScript file. But pay attention, that the pst-optic
files are saved in the above mentioned way, before you run
latex on the documentation file.
