 The PostScript language is a very complex language---far too complex to
 describe in any detail in this document.  Nevertheless there are some things
 in a PostScript file written by `gnuplot` (Note: gnuplot ) that can be
 changed without risk of introducing fatal errors into the file.

 For example, the PostScript statement "/Color true def" (written into the
 file in response to the command `set terminal postscript color`), may be
 altered in an obvious way to generate a black-and-white version of a plot.
 Similarly line colors, text colors, line weights and symbol sizes can also be
 altered in straight-forward ways.  Text (titles and labels) can be edited to
 correct misspellings or to change fonts.  Anything can be repositioned, and
 of course anything can be added or deleted, but modifications such as these
 may require deeper knowledge of the PostScript language.

 The organization of a PostScript file written by `gnuplot` is discussed in
 the text file "ps_file.doc" in the /docs/ps subdirectory.
