Castalia-Delphi-Parser

. Delphi These files make up a hand-written high speed parser for the Object Pascal dialect known as "Delphi". The original work was done by Martin Waldenburg in the late 1990s, and the project was abandoned sometime before 2003, when I found the code and began working on it. I have kept it updated as necessary to work with my project, called "Castalia".
