DCU32INT stands for DCU32 interface, because this program can't extract the complete Pascal source, but the extracted unit interface is almost correct.
This program is a by-product of the FlexT project, but I have done my best to make it useful.
The FlexT specification of DCU file format for 32-bit Delphi versions. This specification is incomplete. Please, let me know if You have more information about this format or if You detect some errors in the specification.
