+# 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.
