5# SYNOPSIS
6#
7#   AX_PROG_JAR
8#
9# DESCRIPTION
10#
11#   AX_PROG_JAR tests for an existing jar program. It uses the environment
12#   variable JAR then tests in sequence various common jar programs.
13#
14#   If you want to force a specific compiler:
15#
16#   - at the configure.in level, set JAR=yourcompiler before calling
17#   AX_PROG_JAR
18#
19#   - at the configure level, setenv JAR
20#
21#   You can use the JAR variable in your Makefile.in, with @JAR@.
22#
23#   Note: This macro depends on the autoconf M4 macros for Java programs. It
24#   is VERY IMPORTANT that you download that whole set, some macros depend
25#   on other. Unfortunately, the autoconf archive does not support the
26#   concept of set of macros, so I had to break it for submission.
27#
28#   The general documentation of those macros, as well as the sample
29#   configure.in, is included in the AX_PROG_JAVA macro.
