Subject Re: SCA source tree and build structure
Date Tue, 03 Apr 2007 17:59:08 GMT

First, thanks for doing this.  I follow what you propose here and makes

Just the concern about having the existing folders as well - I suppose we
will clean that up at some point of time once we get this going smooth.
