-/**
- * Baseline rule class for extension into a "real" parser component.
- *
- * Text_Wiki_Rule classes do not stand on their own; they are called by a
- * Text_Wiki object, typcially in the transform() method. Each rule class
- * performs three main activities: parse, process, and render.
- *
- * The parse() method takes a regex and applies it to the whole block of
- * source text at one time. Each match is sent as $matches to the
- * process() method.
- *
- * The process() method acts on the matched text from the source, and
- * then processes the source text is some way. This may mean the
- * creation of a delimited token using addToken(). In every case, the
- * process() method returns the text that should replace the matched text
- * from parse().
