[rt-users] List of all RT_SiteConfig.pm directives...?

[Brian Benson]

Does anyone know of a list of all of the directives that one can put
inside of RT_SiteConfig.pm?  It may be that my RTFM skills are weak,
but I can not find it anywhere.  Specifically, I am looking for the
'Parse HTML' Directive that Torsten Brumm posted in the "html
transaction appears to have no content, revisited" thread.  But I do
want a complete list.

Thanks,
