This file describes the results of reverse engineering the DCU file format for
Delphi 2.0-8.0, 2005(.net and WIN32), 2006(WIN32 only), Kylix 1.0-3.0.
Note, that the FlexT file describes only the DCU memory layout aspects of file
format. The Pascal code for parsing DCUs (DCU32INT project) is published at
