+       Executes the script using a built-in Lua interpreter. The script is
+       loaded once per execution of cgit, and may be called multiple times
+       during cgit's lifetime, making it a good choice for repeated filters
+       such as the 'email filter'. It responds to three functions:

+       Additionally, cgit exposes to the Lua the following built-in functions:
+
+       'html(str)'::
+               Writes 'str' to the webpage.
+       'html_txt(str)'::

+       'html_url_path(str)'::
+               URL escapes for a path and writes 'str' to the webpage.
