@abstract(Provides a Pascal/Delphi syntax highlighter for SynEdit)
@author(Martin Waldenburg)
@created(1998, converted to SynEdit 2000-04-07)
@lastmod(2000-06-23)
The SynHighlighterPas unit provides SynEdit with a Object Pascal syntax highlighter.
An extra boolean property "D4Syntax" is included to enable the recognition of the
advanced features found in Object Pascal in Delphi 4.
