StandAlone Project File

I have been trying to find in the documentation whether an actual
projects file which can be saved then opened is being worked on, or is
in planning any where.  Does anyone know this answer, or is my question
phrased wrong.  

i.e. In Jbuilder you will save a project as a file and open a project as
a file.  That makes adding a project to source control easier, and it
makes being able to place dependency libs and things in relative paths
to be accessed by the project file easier.  I was wondering if anyone
else is interested in this type of an idea or if it existed.  

If anyone can point me into the right direction that would be great.  I
wouldn't mind working on that section if it is in the works as it is a
feature I could use.  I often have projects that I write for other
people and need to be able to just give it to them with all the same
information I was using to design.  Any help is appreciated.  TIA.
