[Kde-scm-interest] [Proposal] Package splitting with thin meta-repos

Please keep responding, I want this idea stress-tested. I think that what 
you're saying is that by splitting up the modules, it will overcomplicate 
things so that it's too difficult to do manually.

I don't think this is the case, but you might be right.

My comments are inline, as always.

What I AM proposing is like a kdesvnbuild-lite. (Except without the svn. Or 
the build. Mostly just the lite.) But I disagree that we do have two tools 
that fulfill the task of a "kdesvn-build-lite". Kdesvnbuild is great, but 
sometimes you just want to get closer to the underlying software. This 
SHOULDN'T be a piece of real software, just a few helper scripts to make mass 
operations easier.

If you want to clone them manually, then I'm saying that under this system, 
you could do it rather easily, just run down the list of submodules provided 
and clone them one by one. Or write a script to go through the list and...oh,

The only dependency I'd hope for would be sh. (and git) My belief is that if 
these scripts are kept simple, and basically never change, they won't be 
"prone to error". The whole point of being very light wrapper around git 
commands is that if the git commands fail, you can see and fix it.

These aren't essential to operation, they just help. There could be other ways 
to help windows users: initial tarballs with nothing checked out, for example.

I meant it's minor for kde. Ignoring: feel free to take this to the git 
developers, obviously.
