This file adds stuff that's missing in certain versions of Delphi. For instance, the function  IsPathDelimiter  was introduced in Delphi 6, but that would mean QuArK wouldn't be able to compile on Delphi 5 and lower. To solve this problem, an entry for this function has been added to ExtraFunctionality.

The version-definitions of Delphi all come from a single file:  DelphiVer.inc .

Then there are compiler if-checks. Inside them is the missing stuff. Most of it has been taken directly from Delphi source files, with their comment.

Note: All Delphi files that use any of the functions that are declared here or use any of the constants in ExtraFunctionality, should have a ExtraFunctionality in their uses, so when a lower version of Delphi is used, ExtraFunctionality's version is used.
