# SYNOPSIS

#

#   AX_PROG_JAR

#

# 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.
