186 The rules given in this variable are invoked first, followed by
187 whatever rules are specified by the current style.
189 Each member of the list is either a function, or a list of the form:
191 (REGEXP/SYMBOL TEXT-BEGIN-GROUP REPLACEMENT-TEXT/FUNCTION/SYMBOL)
193 REGEXP is a regular expression, or symbol whose value is a regular
194 expression, which is searched for using `re-search-forward'.
195 TEXT-BEGIN-GROUP is the matching group within that regexp which
196 denotes the beginning of the actual text to be marked up.
197 REPLACEMENT-TEXT is a string that will be passed to `replace-match'.
198 If it is not a string, but a function, it will be called to determine
199 what the replacement text should be (it must return a string). If it
200 is a symbol, the value of that symbol should be a string.
202 The replacements are done in order, one rule at a time. Writing
203 the regular expressions can be a tricky business. Note that case
204 is never ignored. `case-fold-search' is always bound to nil
205 while processing the markup rules."

276 within the delimited region.
278 The tags themselves are deleted during publishing, before the

286 the function is called. Wherever point is when the function finishes
