Delphi Collections is a kit to compile run-time Delphi 5 and Delphi 7 packages of collection classes, complete with source code, help files, test harness and some documentation. It has only been tested in Delphi 5 and 7 Professional. It only uses standard RTL classes, so it should be compatible with Standard, Enterprise and Delphi 6 versions but this has not been verified. There is no design-time package because it does not provide components.
