    <title>Command Explanations</title>

    <para>
      <parameter>--enable-vala</parameter>: This switch enables
      building of the Vala bindings. Remove this switch if you don't have
      <xref linkend="vala"/> installed.
    </para>

    <xi:include xmlns:xi="http://www.w3.org/2001/XInclude"
      href="../../xincludes/static-libraries.xml"/>

    <para>
      <parameter>DOC_INSTALL_DIR='$(docdir)'</parameter>: This override
      ensures installing the API documentation into the expected location
      if <xref linkend='gi-docgen'/> is installed.
    </para>

    <para>
      <command>cargo update --precise=0.3.36 time</command>: This updates
      the <filename>Cargo.lock</filename> file to refer the version 0.3.36
      of the time crate for the test suite.  Originally it refers the
      version 0.3.34 which fails to build with Rustc-1.80.0 or later.
    </para>

    <para>
      <option>--disable-introspection</option>: Use this switch if you have
      not installed <application>Gobject Introspection</application>.
    </para>

    <para>
      <option>--disable-gtk-doc</option>: This switch prevents building
      the API documentation, even if <xref linkend="gi-docgen"/> (despite
      the name of the option) is available.
