+# Shell function library for test cases.
+#
+# Note that while many of the functions in this library could benefit from
+# using "local" to avoid possibly hammering global variables, Solaris /bin/sh
+# doesn't support local and this library aspires to be portable to Solaris
+# Bourne shell.  Instead, all private variables are prefixed with "tap_".
+#
+# This file provides a TAP-compatible shell function library useful for
+# writing test cases.  It is part of C TAP Harness, which can be found at
+# <http://www.eyrie.org/~eagle/software/c-tap-harness/>.
