Size of the git repo is too important

[FAMILIAR-project]

Almost 200Mb, despite the fact that it's only a few Mb!

After a fresh git clone, I get:

dn026168:tuxart macher1$ du -h .
1.2M	./tuxart/examples
616K	./tuxart/sources/sprays
640K	./tuxart/sources
1.8M	./tuxart
 20K	./bin
592K	./dist
178M	./.git/objects/pack
  0B	./.git/objects/info
178M	./.git/objects
4.0K	./.git/info
4.0K	./.git/logs/refs/heads
4.0K	./.git/logs/refs/remotes/origin
4.0K	./.git/logs/refs/remotes
8.0K	./.git/logs/refs
 12K	./.git/logs
 48K	./.git/hooks
4.0K	./.git/refs/heads
  0B	./.git/refs/tags
4.0K	./.git/refs/remotes/origin
4.0K	./.git/refs/remotes
8.0K	./.git/refs
178M	./.git
180M	.

so .git seems responsible.
Is it due to the history?
