#
# 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.
