[PD] flatspace? What the hell it is

[Georg Holzmann]

Hallo!

> Hello, anyone could tell the meaning of "flatspace"?

As far as I understand it now, it is an "older" buildsystem, made by 
Günther.
The new one is the one with the libdir format.

However, there are still lot's of externals in the flatspace, which are 
not in the libdir format yet (especially one-object externals).

And there are also many doubled externals, which are in the libdir and 
the flatspace.
I just tried to delete the doubled objects, but we should discuss if 
this is useful and doesn't break other things ...
