2 %% This is file `lgrind.sty',
3 %% generated with the docstrip utility.
4 %%
5 %% The original source files were:
6 %%
7 %% lgrind.dtx (with options: `package')
8 %%
9 %% LGrind is used to format source code of different programming
10 %% languages for LaTeX.
11 %%
12 %% LGrind is a minor adaptation of Jerry Leichter's tgrind for LaTeX,
13 %% which was a notable improvement upon Van Jacobsen's tgrind for
14 %% plain TeX, which was adapted from vgrind, a troff prettyprinter.
15 %%
16 %% Based on Van Jacobson's ``tgrindmac'', a macro package for TeX.
17 %% Modified, 1987 by Jerry Leichter. Put '@' in all internal names.
18 %% Modified, 1991 by George Reilly. Changed name from tgrind to lgrind.
19 %% Modified, 1995 by Michael Piefel. Made it work with \LaTeXe.
