-#  TestRunner.sh - This script is used to run arbitrary unit tests.  Unit
-#  tests must contain the command used to run them in the input file, starting
-#  immediately after a "RUN:" string.
+#  TestRunner.sh - This script is used to run the deja-gnu tests exactly like
+#  deja-gnu does, by executing the Tcl script specified in the test case's 
+#  RUN: lines. This is made possible by a simple make target supported by the
+#  test/Makefile. All this script does is invoke that make target. 
 #
-#  This runner recognizes and replaces the following strings in the command:
+#  Usage:
+#     TestRunner.sh {script_names}
 #
-#     %s - Replaced with the input name of the program, or the program to
-#          execute, as appropriate.
-#     %llvmgcc - llvm-gcc command
-#     %llvmgxx - llvm-g++ command
-#     %prcontext - prcontext.tcl script
+#     This script is typically used by cd'ing to a test directory and then
+#     running TestRunner.sh with a list of test file names you want to run.
