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.
