+# Simple test harness infrastructure

+# Copyright 2005 by Rob Landley
+
+# 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.
+#
+# 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 "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.
+#
+# The "optional" function is used to skip certain tests (by setting the
+# environment variable SKIP), ala:
+#   optional CFG_THINGY
+#
+# The "optional" function checks the environment variable "OPTIONFLAGS",
+# which is either empty (in which case it always clears SKIP) or
+# else contains a colon-separated list of features (in which case the function
+# clears SKIP if the flag was found, or sets it to 1 if the flag was not found).
