47 <para>This package and the next two (Expect and DejaGNU) are
48 installed to support running the test suites for GCC and Binutils and other
49 packages. Installing three packages for testing purposes may seem
50 excessive, but it is very reassuring, if not essential, to know that the
51 most important tools are working properly. These packages are required
52 to run the test suites in <xref linkend="chapter-building-system"/>.</para>

54 <para>Note that the Tcl package used here is a minimal version needed
