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.
