[WiX-users] heat / "SourceDir"

[Sascha B. <sas...@gm...>]

Hi,

I recall in a recent thread that heat generated .wxs files will search
for files with the path "SourceDir\..." in folders specified with the
"-b" switch to light, but can't find anything in the documentation
about this feature/

Currently I'm just doing a search/replace and replacing "SourceDir\"
with a $(var.xyz) preprocessor variable on the heat output, is there
any benefit/problems with either method?
