      This package needs <command>gi-docgen</command> to be built.  Set up
      a Python virtual environment to run it:

<screen><userinput remap="pre">python3 -m venv pyvenv &amp;&amp;

      To test the results, issue: <command>make -k check</command>.  During
      testing some binaries are rebuilt with different debug level, so you
      should run <command>make</command> again after the test, to ensure
      everything ready to be installed.
