7 # AX_PROG_JAVA_WORKS

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.
