Syntax file for Borlands Delphi/Kylix
This is a mirror of http://www.vim.org/scripts/script.php?script_id=60
This syntax file for Borlands ObjectPascal (Delphi,Kylix) is derived from the original pascal.vim. Some basic VCL-Classes are added and some keywords have new meanings (e.g. read/write, assign). It also includes a different color scheme.
