5# SYNOPSIS

7# AX_PROG_JAVA_WORKS
8#
9# DESCRIPTION
10#
11# Internal use ONLY.
12#
13# Note: This is part of the set of autoconf M4 macros for Java programs.
14# It is VERY IMPORTANT that you download the whole set, some macros depend
15# on other. Unfortunately, the autoconf archive does not support the
16# concept of set of macros, so I had to break it for submission. The
17# general documentation, as well as the sample configure.in, is included
18# in the AX_PROG_JAVA macro.
