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

    <para>
      <option>--enable-threads</option>: This switch forces the package
      to build with threads 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>

    <para>
      <command>sed -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.
