 file .emacs-project

If I have a project.el based plugin,  and  I wanna use them in a 
directory not under VC. Add an mark to force project.el work is easier 
than modify the source of plugin or initialize VC system.

And this  can also be used as a side solution to use project.el in 
unsupported VCed project in Emacs (AFAIK, P4(Perforce) is not supported 
by vc.el).

IMO, a plain project is like a transient project.
