There should be linked folders to the source directory and to the subproject 
directories in the "Project Explorer" view. Are they there for you ?

The subproject links only work with Eclipse 3.6 (Helios) and newer.

I am also working on improving the situation, by adding support for source 
groups in Eclipse and by detecting the version of Eclipse.
