Delete history of on your own SparkleShare server

SparkleShare is a little Open Source software that allows users to share documents and files with version control and client side encryption system. To put it simply, it acts like Dropbox or Ubuntu One, but it works on top of a Git repository. This means that, if you want, you can simply setup you own a SparkleShare server and share office documents with your colleagues having all infrastructure under your control using Git. This is exactly my office's approach and it works very well. There's only an issue about this: sometimes you need to share big files for a limited period of time. Actually, SparkleShare (v 1.1) has no feature to clear history and this means that Git repositories contain all data needed to access to revisions. In simple words: each repository has disk size equal to the sum of each version of each file (also deleted). In this case it could be useful to clear repository history in order to free a lot of disk space both on server and client.
