[Haskell-cafe] ANN: hit a reimplementation of git storage in haskell.

Hi Haskellers,

I just want to announce the hit project [1], which is a reimplementation of low 
level git operations to read *AND* write to a git repository. It support reading 
from anything i threw at it (loose objects, packed objects, deltas), a subset of 
revisions specifier (man gitrevisions), and writing new objects (blob, tree, 
commit, tag).

I don't necessarily want to re-implement git itself (although patches welcome if 
someone want to go in this direction), and as such the project is a bit of a toy 
to investigate git storage (for another project of mine) and superseeding my own 
libgit project (for yet another project). Yet it should be completely functional 
and have good performance.

A few word of the implementation: it's very IO based at the moment; The way 
things are done by git, doesn't necessarily cope with pure and nice stuff if 
performance need to follow. That said it should still be easier to understand 
than reading the git source :-)

Any comments welcome,
