git-unpack-objects

I was playing around with git repack and decided to "undo" the repack
I did using git-unpack objects.  Below is the output:

[jwboyer@vader linux-2.6]$ git-unpack-objects <
.git/objects/pack/pack-497d1e639572013de48eeb00cb95738d2ca959e1.pack
Unpacking 236950 objects
 100% (236950/236950) done
[jwboyer@vader linux-2.6]$ ls -l .git/objects/
total 8
drwxrwxr-x 2 jwboyer jwboyer 4096 May  1 17:48 info
drwxrwxr-x 2 jwboyer jwboyer 4096 May  1 17:48 pack
[jwboyer@vader linux-2.6]$


As you can see, the objects don't seem to get unpacked back into the
.git directory.  So either I am misunderstanding what that command is
supposed to do, or it isn't working properly.

Any ideas?

thx,
