 # 4.) Create a <SubTest>.cmake file for each sub-test named above
 # containing the actual test code.  Optionally create files
 # containing expected test results:
-#   <SubTest>-result.txt = Process result expected if not "0"
-#   <SubTest>-stdout.txt = Regex matching expected stdout content
-#   <SubTest>-stderr.txt = Regex matching expected stderr content
+#   <SubTest>-result.txt  = Process result expected if not "0"
+#   <SubTest>-stdout.txt  = Regex matching expected stdout content
+#   <SubTest>-stderr.txt  = Regex matching expected stderr content
+#   <SubTest>-check.cmake = Custom result check
 # Note that trailing newlines will be stripped from actual test
 # output before matching against the stdout and stderr expressions.
+# The code in <SubTest>-check.cmake may use variables
+#   RunCMake_TEST_SOURCE_DIR = Top of test source tree
+#   RunCMake_TEST_BINARY_DIR = Top of test binary tree
+# and an failure must store a message in RunCMake_TEST_FAILED.
