-# This file defines two functions, "testing" and "optionflag"
+# This file defines two main functions, "testcmd" and "optional". The
+# first performs a test, the second enables/disables tests based on
+# configuration options.
 
 # The following environment variables enable optional behavior in "testing":
 #    DEBUG - Show every command run by test script.
 #    VERBOSE - Print the diff -u of each failed test case.
 #              If equal to "fail", stop after first failed test.
-#    SKIP - do not perform this test (this is set by "optionflag")

+# The "testcmd" function takes five arguments:
 #	$1) Description to display when running command
 #	$2) Command line arguments to command
 #	$3) Expected result (on stdout)
 #	$4) Data written to file "input"
 #	$5) Data written to stdin
 #
-# The exit value of testing is the exit value of the command it ran.
+# The "testing" function is like testcmd but takes a complete command line
+# (I.E. you have to include the command name.) The variable $C is an absolute
+# path to the command being tested, which can bypass shell builtins.
+#
+# The exit value of testcmd is the exit value of the command it ran.
 #
 # The environment variable "FAILCOUNT" contains a cumulative total of the
 # number of failed tests.
