The JEDI Code Library (JCL) consists of a set of thoroughly tested and fully documented utility functions and non-visual classes which can be instantly reused in your Delphi and C++ Builder projects.
The reasons for my thumbs down are three hours spent in the struggle with "recommended" automated installer and obscure manual installation instructions. Installer tends to construct really really long relative pathnames eg: ..\..\..\..\..\..\..\..\DOCUME~1\RADSTU~1\LIBRAR~1\JEDI\jcl\jcl\lib\d7 instead of indeed shorter absolute pathnames, causing a buffer overflow in Delphi 7's DCC. Manual installation doc seems to be not updated since version 1.x
Nice project! You did a great job. Thank you!
