Splitting git repository

Splitting git repository.
============

* Do the clone and the filter:
   
	`git clone --no-hardlinks foo bar; cd bar`
	
	`git filter-branch --subdirectory-filter subdir/you/want HEAD`

* Remove every reference to the old history. "origin" was keeping
   track of your clone, and “original” is where filter-branch saves
   the old stuff:

	`git remote rm origin`
	
	`rm -r .git/refs/original/`

	`git reflog expire --expire=now --all`

* Even now, your history might be stuck in a packfile that fsck won't touch. Tear it to shreds:
   
	`git gc --aggressive`

* Only now does git-fsck find unused commits! Now git-prune will delete them:

	`git prune`
