/**
* Formatter that does regexp replacement.
*
* To use this formatter, a two-part argument must be given. The parts are
* separated by a comma. To indicate the comma character, use an escape
* sequence: \,
* For inserting newlines and tabs in arguments, use \n and \t, respectively.
*
* The first part is the regular expression to search for. Remember that any commma
* character must be preceded by a backslash, and consequently a literal backslash must
* be written as a pair of backslashes. A description of Java regular expressions can be
* found at:
* http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html
*
* The second part is the text to replace all matches with.
*
* For instance:
* \format[Replace(and,&)]{\author} :
* will output the "author" field after replacing all occurences of "and"
* by "&"
*
* \format[Replace(\s,_)]{\author} :
* will output the "author" field after replacing all whitespace
* by underscores.
*
* \format[Replace(\,,;)]{\author} :
* will output the "author" field after replacing all commas by semicolons.
*
