Modified versions of some Delphi 2010 RTL units which could reduce your binary size. Main reduction is for non-VCL projects which use Classes unit: -150 kB! Carefully read notes in units' headers! To use this modified units you'll need to add path to them to the Project options => Delphi compiler => Search path. If you use units which use some MiniRTL units you'll have to copy them into MiniRTL folder. Other Delphi versions not included, sorry.
