Hm, fails for me with:

Traceback (most recent call last):
  File "../make-directive-index.py", line 284, in make_page
    _extract_directives(directive_groups, formatting, page)
  File "../make-directive-index.py", line 172, in _extract_directives
    t = xml_parse(page)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "../make-directive-index.py", line 292, in <module>
    f.write(xml_print(make_page(*sys.argv[2:])))
  File "../make-directive-index.py", line 286, in make_page
    raise ValueError("failed to process " + page)
ValueError: failed to process ../man/sd_is_fifo.xml

lxml is only used if available, make sure to have it installed if you
want to see it.
