names.

= **Constants:**

ALL_CROSSREF_REGEXP:
### Version of CROSSREFREGEXP used when --hyperlink-all is specified.

CLASS_REGEXP_STR:
### Regular expression to match class references

  1. There can be a '' in front of text to suppress the cross-reference
  2. There can be a '::' in front of class names to reference from the
     top-level namespace.
  3. The method can be followed by parenthesis (not recommended)

CROSSREF_REGEXP:
### Regular expressions matching text that should potentially have
  cross-reference links generated are passed to add_regexp_handling.
### Note that these expressions are meant to pick up text for which
  cross-references have been suppressed, since the suppression
  characters are removed by the code that is triggered.

### Regular expression to match method arguments.

METHOD_ARG_REGEXP_STR:
### Regular expression to match a single method argument.

METHOD_REGEXP_STR:
