5# SYNOPSIS
6#
7# AX_CHECK_CLASSPATH
8#
9# DESCRIPTION
10#
11# AX_CHECK_CLASSPATH just displays the CLASSPATH, for the edification of
12# the user.
13#
14# Note: This is part of the set of autoconf M4 macros for Java programs.
15# It is VERY IMPORTANT that you download the whole set, some macros depend
16# on other. Unfortunately, the autoconf archive does not support the
17# concept of set of macros, so I had to break it for submission. The
18# general documentation, as well as the sample configure.in, is included
19# in the AX_PROG_JAVA macro.
