+# SYNOPSIS
+#
+#   AC_PERL_MODULE_VERSION([MODULE VERSION], [ACTION-IF-TRUE], [ACTION-IF-FALSE])
+#
+# DESCRIPTION
+#
+#   Checks to see if the list of 'Module Version' are avaiable in the
+#   system. If all the modules in the list are avaiable ACTION-IF-TRUE is
+#   executed. Case one module is not avaiable ACTION-IF-FALSE is executed
+#   and the macro execution is aborted. NOTE: Perl is needed.
+#
+#   Example:
+#
+#     AC_PERL_MODULE_VERSION(CGI::Test 0.104 CGI::Ajax 0.694, ,
+#        AC_MSG_ERROR(Need some Perl modules))
