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 test suites, all supported by a single test
harness. DejaGnu is written in Expect, which in turn uses Tcl.
