##### http://autoconf-archive.cryp.to/ac_prog_java_works.html # # SYNOPSIS # # AC_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 AC_PROG_JAVA macro. # # LAST MODIFICATION # # 2000-07-19 # # COPYLEFT # # Copyright (c) 2000 Stephane Bortzmeyer # # 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.
