"""Decorator used to register a web command handler.
The decorator takes as its positional arguments the name/path the
command should be accessible under.
When called, functions receive as arguments a ``requestcontext``,
``wsgirequest``, and a templater instance for generatoring output.
The functions should populate the ``rctx.res`` object with details
about the HTTP response.
The function returns a generator to be consumed by the WSGI application.
For most commands, this should be the result from
``web.res.sendresponse()``. Many commands will call ``web.sendtemplate()``
to render a template.
Usage:
