GraphPs GraphPs is a Caml Light library that provides a module that can be substituted to the usual graphics drawings module Graphics, available from the Caml distribution. GraphPs provides a module also named Graphics, that has (almost) the same signature as the original Graphics module. Using the GraphPs Graphics module, your Caml drawing programs generate PostScript files (that can be encapsulated into TeX or LaTeX files), instead of drawing graphics directly onto the screen. The PostScript program is output when evaluating ``close_graph ()''. Intended usage is a two phases process: -- write a regular Caml program (either batch or interactive) using the regular graphics library. -- substitute the graphps library to the regular graphics library (for instance you can just change the Caml library load path to obtain linking of graphps in place of graphics) to obtain a new executable that produces ps commands instead of graphics commands. Run the new executable to produced a PostScript file corresponding to the drawing produced by your Caml program. Your original Caml program should work fine with no modification when using the Graphics module provided by GraphPs (as far as your Caml program ends with close_graph ();;). See the INSTALL file to intall the library. Have fun with GraphPs. Pierre Weis.
