1 % This is chkconfig.ltx, a script which tries to autodetect and
2 % document your LaTeX configuration.
3 % Author: Jean-Marc Lasgouttes (Jean-Marc.Lasgouttes@inria.fr)
4 % with minimal changes by Asger Alstrup (alstrup@diku.dk).
6 % This script should only be run from the configure script to update
7 % the files textclass.lst and doc/LaTeXConfig.lyx
9 % This script is in fact a complete rewrite of the original chkconfig
10 % script. Expect bugs.
12 %%% If you want to add new packages/documentclasses to be recognized,
13 %%% read the explanation that follow and jump to the section 'Actual
14 %%% inspection code' below. You do not need to understand the ugly
15 %%% LaTeX code below to help improving chklatex.ltx :-)
17 %%% If you want to add the new package <name>, all you need most of
18 %%% the times is a two-steps work:
19 %%% 1- Add the command \TestPackage{<name>}. The syntax is:
20 %%% \TestPackage[<file>]{<name>}, which tests whether <name>.sty
21 %%% (or <file>, if this optional parameter is provided) exists.
22 %%% 2- Add a description for <name> in doc/LaTeXConfig.lyx.in,
23 %%% containing in particular a line like
24 %%% Found @chk_<name>@
25 %%% This line will be replaced at configure time by the proper text.
27 %%% For document classes, things are even simpler, since you do not
28 %%% need to edit this file. Just put your layout file in some place
29 %%% where LyX can find it and add if you wish a description in
30 %%% LaTeXConfig.lyx.in, as described above.

48 %%% Some useful macros.
49 % Several commands are defined to test for packages:
50 % \AddLayout{<layout>} adds an entry for <layout> in textclass.lst
51 % \AddVariable{<name>}{<value>} creates a new variable chk_<name>,
52 % and gives it the value <value>.
53 % \TestDocClass[<file>]{<name>} tests whether <name>.cls (or <file>,
54 % if it is provided) exists and creates a new entry with
55 % \AddLayout if this is the case. Note that you will probably not
56 % need to use this directly, since the configure script generates
57 % the needed macro calls automatically.
58 % \TestPackage[<file>]{<name>} tests whether <name>.sty (or <file>,
59 % if it is provided) exists.
60 % Both commands call \AddVariable to give value 'yes' or 'no' to
61 % the variable chk_<name>.
