Parcel is a simple library which allows normal ruby objects to maintain a series of files stored in one or more repositories which are accessible through normal ruby attributes. Possible repositories include Zip Files, Tar Files, Subversion Repos, Repos, GridFS Zips, etc. It also provides an common and easy to use interface to all these repositories (i.e. more ruby like than RubyZip), and works with ActiveRecord but doesn't depend on it.
