Subject: Implement rudimentary garbage collection.
X-Git-Url: http://git.vrable.net/?a=commitdiff_plain;h=2911a4279cce1e880793c934ce90a187856c7c92;hp=2911a4279cce1e880793c934ce90a187856c7c92;p=cumulus.git

Implement rudimentary garbage collection.

Implement a garbage collection method in cumulus-util which will search for
files not referenced by any current snapshots and delete them.  This still
doesn't let snapshots themselves be deleted automatically, but after
manually deleting a snapshot this will quickly delete all other old files.
