+# SYNOPSIS
+#
+#   AX_PROG_MAVEN_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
+#
+# DESCRIPTION
+#
+#   Makes sure that maven supports the version indicated. If true the shell
+#   commands in ACTION-IF-TRUE are executed. If not the shell commands in
+#   ACTION-IF-FALSE are run. The $MAVEN_VERSION variable will be filled with
+#   the detected version.
+#
+#   This macro uses the $MAVEN variable to perform the check. If $MAVEN is not
+#   set prior to calling this macro, the macro will fail.
+#
+#   Example:
+#
+#     AC_PATH_PROG([MAVEN],[mvn])
+#     AC_PROG_MAVEN_VERSION([3.0.0],[ ... ],[ ... ])
+#
+#   Searches for Maven, then checks if at least version 3.0.0 is present.
