lyx_mirror/lib/chkconfig.ltx

% This is chkconfig.ltx, a script which tries to autodetect and
%    document your LaTeX configuration.
% Author: Jean-Marc Lasgouttes (Jean-Marc.Lasgouttes@inria.fr)
% with minimal changes by Asger Alstrup (alstrup@diku.dk).
%
% This script should only be run from the configure script to update
% the files textclass.lst and doc/LaTeXConfig.lyx
%
% This script is in fact a complete rewrite of the original chkconfig
% script. Expect bugs.

%%% If you want to add new packages/documentclasses to be recognized,
%%% read the explanation that follow and jump to the section 'Actual
%%% inspection code' below. You do not need to understand the ugly
%%% LaTeX code below to help improving chkconfig.ltx :-)
%%%
%%% If you want to add the new package <name>, all you need most of
%%% the times is a two-steps work:
%%% 1- Add the command \TestPackage{<name>}. The syntax is:
%%%    \TestPackage[<file>]{<name>}, which  tests whether <name>.sty
%%%    (or <file>, if this optional parameter is provided) exists.
%%% 2- Add a description for <name> in doc/LaTeXConfig.lyx,
%%%    containing in particular a line like
%%%         Found: [InsetInfo]
%%%    where [InsetInfo] is obtained by entering in the minibuffer (Alt+X)
%%%    info-insert package <name>
%%%    This inset will automatically display a boxed "yes" or "no"
%%%    depending on the availability of the package.
%%%
%%% For document classes, things are even simpler, since you do not
%%% need to edit this file. Just put your layout file in some place
%%% where LyX can find it and add if you wish a description in
%%% LaTeXConfig.lyx, as described above but using
%%% "info-insert textclass <name>" instead of "info-insert package <name>".

%%% Some useful macros.
%   Several commands are defined to test for packages:
%    \AddLayout{<layout>} adds an entry for <layout> in textclass.lst
%    \AddVariable{<name>}{<value>} creates a new variable chk_<name>,
%      and gives it the value <value>.
%    \TestDocClass{<name>}{<command>} if layout <name> has not already
%      been tested for, execute <command>. Note that you will
%      probably not need to use this directly, since the configure
%      script generates the needed macro calls automatically.
%    \TestPackage[<file>]{<name>} tests whether <name>.sty (or <file>,
%      if it is provided) exists.
%   Both commands call \AddVariable to give value 'yes' or 'no' to
%   the variable chk_<name>.
