void Parser::MeParser::revise	(	SentenceReader *	sentenceReader,
		char const *	actionFile = 0
	)			[virtual]

Produce a revision of a document parses, using either a model or an action file.

If an actionFile is provided, it must contain a list of actions, one per line, to apply to the parse trees, otherwise the actions to perform revisions are determined using the model.
