Hi, Mike.

I won't go into "comparison", and I know some people will fill

There actually were a few incompatible ones but they were only
during the first few weeks of life (the beginning of time is Apr
7th, 2005):

 - The tree object was originally a flat "manifest" but was
   converted to hierarchy of trees (Apr 10th, 2005)

 - The metainformation directory was originally called .dircache,
   but renamedto ".git" (Apr 11th, 2005)

 - The order of compression and hashing was swapped and older
   objects needed conversion (Apr 20, 2005)
