files: MHS, XMP, MSS,

directories:  data/, etc/, pcores, and any application source code dirs

Pretty much everything else is a generated file/directory

We use SVN internally which can handle symlinks.  You can always copy 
the directory inrto your HW project, but there are issuse with that as well.

Another option is to specify a relative path to the edk_user_repository 
directory - you can set that in the XMP file or via the XPS gui.

It's sort of documented, but not completely.  Appendix C of est_rm.pdf 
is the best place to look.

Right here!

We could look at adding some doco here:

it's just a question of time...
