# =========================================================================== # http://www.gnu.org/software/autoconf-archive/ax_prog_java_works.html # =========================================================================== # # SYNOPSIS # # AX_PROG_JAVA_WORKS # # DESCRIPTION # # Internal use ONLY. # # Note: This is part of the set of autoconf M4 macros for Java programs. # It is VERY IMPORTANT that you download the whole set, some macros depend # on other. Unfortunately, the autoconf archive does not support the # concept of set of macros, so I had to break it for submission. The # general documentation, as well as the sample configure.in, is included # in the AX_PROG_JAVA macro. # # LICENSE # # Copyright (c) 2008 Stephane Bortzmeyer <bortzmeyer@pasteur.fr> # # This program is free software; you can redistribute it and/or modify it # under the terms of the GNU General Public License as published by the # Free Software Foundation; either version 2 of the License, or (at your # option) any later version. # # This program is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
