I just want to give you a warning about incremental compilation. 
Currently it doesn't work out that well in D due to various reasons. You 
can search the newsgroups archive for extended posts about this. But to 
mention some of the reasons:

DMD doesn't output all symbols to all object files resulting in missing 
symbols when doing incremental compilation. I think it's mostly template 
symbols that cause problems. I've heard that using the -lib flag, DMD 
will output all symbols to all object files.

Since header/import files are rarely used in D you often need to 
recompile quite many files even if you only do localized changes, 
specially compared to C/C++ using header files.
