Module documentation for 1.0.15
There are no documented modules for this package.
Ebnf2ps generates nice looking syntax diagrams in EPS and FIG format from EBNF specifications and from yacc, bison, and Happy input grammars. The diagrams can be immediatedly included in TeX/LaTeX documents and in texts created with other popular document preparation systems.

Two environment variables may need to be set:
Find out where your
.afm-files (Adobe font metric files). Then set the environment variable
AFMPATHwhen running the program. The
.afm-files are absolutely necessary. If you don’t find them complain to your system administrator or get them yourself. One possible source is here.
Set the environment variable
RGBPATHto contain the directory where your X installation stores its color data base (usually
/usr/lib/X11). There are fallback color definitions for the 8 digital colors (black, white, blue, green, cyan, red, magenta, yellow), so nothing needs be done if that’s enough for you.
Note: for Mac OS X, the default
/opt/X11/share/X11has been provided and will work automatically, if you have installed X using XQuartz.
With Peter Thiemann’s permission, I am now maintaining this package, starting with version 1.0.12.
I first used this software in 1995 (!), so it was a nostalgia trip finding it again in 2014 and reviving it. PostScript is no longer in fashion, but one can still use this tool and then convert PostScript to PDF.
