-README for LyX configure stuff
-Author: Jean-Marc Lasgouttes (Jean-Marc.Lasgouttes@inria.fr)
------------------------------------------------------------------------
-
-This directory contains the things used to build the configure
-scripts. The file present here are the following:
-
-makefile		a simple makefile to build configure script
-acconfig.h		template file describing src/config.h.in
-aclocal.m4		local macros for configure.in
-configure.in		the template from which configure is built
-lib_configure.m4	the template from which lib/configure is built
-install-sh		shell script used when no good install program
-			is found
-mkinstalldirs		shell script used to create installation dirs.
-stamp-h.in		file used by Makefile to check dependencies
-hack-gcc		a shell script to work around possible gcc bugs
-
-How to use the makefile
------------------------
-
-When you make a modification to some configure component, just type
-'make', with the config/ directory being current. This will create
-configure, lib/configure and config.h.in. Do *not* try to run directly
-autoconf or autoheader. Note that these scripts require autoconf 2.12
-or later.
-
-There is also a target 'clean' which delete backup files, etc.
-
-Note: please do not rename `makefile' to `Makefile'! This name was
-chosen in order avoid being excluded from LyX patches...
