+# SYNOPSIS
+#
+#   AX_PROG_PERL_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
+#
+# DESCRIPTION
+#
+#   Makes sure that perl 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. Note if $PERL is not set (for example by
+#   running AC_CHECK_PROG or AC_PATH_PROG) the macro will fail.
+#
+#   Example:
+#
+#     AC_PATH_PROG([PERL],[perl])
+#     AX_PROG_PERL_VERSION([5.8.0],[ ... ],[ ... ])
+#
+#   This will check to make sure that the perl you have supports at least
+#   version 5.8.0.
+#
+#   NOTE: This macro uses the $PERL variable to perform the check.
+#   AX_WITH_PERL can be used to set that variable prior to running this
+#   macro. The $PERL_VERSION variable will be valorized with the detected
+#   version.
