A GSoC project.  Was waiting for comments from mentors and
stakeholders, but nothing seems to be happening, other than breakage
fixes on Cygwin.  May discard.

I was planning on continuing to work on this topic as part of my Bachelor
Thesis.  I had a brief discussion with Thomas Rast on IRC about this
today.  Because I am planning to implement an api for partial loading
we decided it's probably best to hold off until that's implemented,
because parts of this series may change and it's going to take me a while
to implement the api.

As for the actual look of the api, I think something along the lines of
what was discussed at [1] would fit well.

The commands would then learn to use this api. (First the commands that
just read the index and later the commands that read and write the index,
but for that the api will have to support writing the index)
