# 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.
