  <sect2 role="commands">
    <title>Command Explanations</title>

    <para><parameter>--enable-threads</parameter>: This switch forces the package
    to build with thread support.</para>

    <para><command>make install-private-headers</command>: This command is
    used to install the <application>Tcl</application> library interface
    headers used by other packages if they link to the
    <application>Tcl</application> library.</para>

    <para><command>ln -v -sf tclsh&tcl-ver; /usr/bin/tclsh</command>: This
    command is used to create a compatibility symbolic link to the
    <command>tclsh&tcl-ver;</command> file as many packages expect a file
    named <command>tclsh</command>.</para>

    <!-- This is removed per discussion and fairly vigorous testing
    <para><command>sed -i -e ... tclConfig.sh</command>: The
    <application>Tcl</application> package expects that its source tree is
    preserved so that packages depending on it for their compilation
    can utilize it. This <command>sed</command> removes the references to the
    build directory and replaces them with saner system-wide locations.</para>

    <para><command>install ...</command>: These commands install the internal
    headers into a system-wide location.</para>

    <para><command>ln -v -sf ...</command>: These commands create compatibility
    symbolic links.</para>
