                     81: Hilighting of object-oriented Forth code is achieved, by appending either

                     89: 
                     90: MATCHER is either a list of strings to match, or a REGEXP.
                     91:    If it's a REGEXP, it should not be surrounded by '\\<' or '\\>', since 
                     92:    that'll be done automatically by the search routines.
                     93: 
                     94: TYPE should be one of 'definiton-starter', 'definition-ender', 'compile-only',
                     95:    'immediate' or 'non-immediate'. Those information are required to determine
                     96:    whether a word actually parses (and whether that parsed text needs to be
                     97:    hilighted).
                     98: 
                     99: HILIGHT is a cons cell of the form (FACE . MINIMUM-LEVEL)
                    100:    Where MINIMUM-LEVEL specifies the minimum value of `forth-hilight-level',
                    101:    that's required for matching text to be hilighted.
                    102: 
                    103: PARSED-TEXT specifies whether and how a word parses following text. You can
                    104:    specify as many subsequent PARSED-TEXT as you wish, but that shouldn't be
                    105:    necessary very often. It has the following form:
                    106:    (DELIM-REGEXP SKIP-LEADING-FLAG PARSED-TYPE HILIGHT)
                    107: 
                    108: DELIM-REGEXP is a regular expression that should match strings of length 1,
                    109:    which are delimiters for the parsed text.
                    110: 
                    111: A non-nil value for PARSE-LEADING-FLAG means, that leading delimiter strings
                    112:    before parsed text should be skipped. This is the parsing behaviour of the
                    113:    Forth word WORD. Set it to t for name-parsing words, nil for comments and
                    114:    strings.
                    115: 
                    116: PARSED-TYPE specifies what kind of text is parsed. It should be on of 'name',
