Internal Program Version: DejaGNU  1.6.3

DejaGnu is a framework for testing other programs. Its purpose
is to provide a single front end for all tests. Think of it as
a custom library of Tcl procedures crafted to support writing
a test harness. A test harness is the testing infrastructure
that is created to support a specific program or tool. Each
program can have multiple testsuites, all supported by a single
test harness. DejaGnu is written in Expect, which in turn uses
Tcl -- Tool command language.
