@majorheading Description

AX_PROG_JAR tests for an existing jar program. It uses the environment
variable JAR then tests in sequence various common jar programs.

If you want to force a specific compiler:

- at the configure.in level, set JAR=yourcompiler before calling
AX_PROG_JAR

- at the configure level, setenv JAR

You can use the JAR variable in your Makefile.in, with @@JAR@@.

Note: This macro depends on the autoconf M4 macros for Java programs. It
is VERY IMPORTANT that you download that 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 of those macros, as well as the sample
configure.in, is included in the AX_PROG_JAVA macro.
