Well, this is only simple if all the subsequent configuration stuff 
knows how to handle this. When you create the command lines for all the 
build steps, you need to know where all the source files live. If they 
are the true source files, they should be taken from the source 
directory; however if they are generated (e.g. by yacc), they need to be 
taken from the build directory. This lookup is exactly what vmount was 
meant to help with.
