+This directory contains tests for the ATM stuff. Specific tests for HARP
+are in the harp subdirectory and are not automatically run. All
+other tests can be run from the top-level or from their sub-directories by
+starting RunTest.sh.
+
+These tests require ports/net/atmsupport to be installed - the
+scripts will remind you if they cannot find the package.
+
+harp			HARP tests
+proto_sscfu		test suite for the SSCF at the user interface
+proto_sscop		test suite for the SSCOP protocol
+proto_uni		test suite for the UNI protocol
