This is a free reimplementation of Kernighan and Bentley's grap
|
|
language for typesetting graphs, as described in ``Grap-A Language for
|
|
Typesetting Graphs, Tutorial and User Manual,'' by Jon L. Bentley and
|
|
Brian W. Kernighan, revised May 1991, which is the primary source for
|
|
information on how to use grap.
|
|
|
|
grap is a pic pre-processor. It takes commands embedded in a troff
|
|
source file which are surrounded by .G1 and .G2 macros, and rewrites
|
|
them into pic commands to display the graph.
|
|
|
|
Because grap is a pic preprocessor, and GNU pic will output TeX, it is
|
|
possible to use grap with TeX.
