does anyone know of any good description of delphi's build system? (i know it's using MS Build.) i'm using delphi 2009.

i wanted to set up a variation of the Debug build configuration that (often) has different defines (d2009 seems to call them "preprocessor symbols").

the problem i'm having is that--even though i turned off "inherit" for "Base" and "Debug"--have only very limited control. for example, i can't get rid of FastMM_.

    </PropertyGroup>

i even had to edit it today with notepad to get rid of a DCC define that the delphi UI doesn't seem to give access to. (it said "From Delphi Compiler" for the item i couldn't remove.)

does anyone know a good primer on the use of this feature in delphi?

thank you!
