And another reason to make our SVN source tree structure modularized.

I'm seeing more and more people afraid of adding anything "big" to our tree.
But this is just natural for a project that aims to become a fully fledged operating
system!

The worst thing would be an OS that can be quickly compiled from scratch and then needs
lots of binary blobs to be useful. Even worse, those binary blobs could hardly be verified
and patched.
Don't forget we already had that with our schannel.dll implementation that depended on
an external GnuTLS binary. Fortunately, this is fixed by now and ReactOS supports TLS out
of the box.
I would like to see the same for a Mesa/Gallium/llvmpipe stack.
Having one somewhere hidden in RAPPS, but not in an out of the box ReactOS installation
from the ReactOS giveaway CDs would be very disappointing...

I also understand the group though who wants the default ReactOS build to be lightweight.
So maybe Mesa/Gallium/llvmpipe could become part of another module which is added through
our "modules" subdirectory.
Our current SVN setup with just one ReactOS repository does not really encourage adding
new modules. Another reason for a move to Git where everybody could easily put his big
module into an own repository :)


Cheers,

Colin
