The CernVM-FS python package allows for the inspection of CernVM-FS repositories
using python. In particular to browse their file catalog hierarchy, inspect
CernVM-FS repository manifests (a.k.a. .cvmfspublished files) and the history of
named snapshots inside any CernVM-FS 2.1 repository.

Example Usage:

   import cvmfs

   repo = cvmfs.RemoteRepository('http://cvmfs-stratum-one.cern.ch/opt/boss')
   print 'Last Revision:' , repo.manifest.revision , repo.manifest.last_modified
   root_catalog = repo.retrieve_root_catalog()
   print 'Catalog Schema:' , root_catalog.schema
   for nested_catalog_ref in root_catalog.list_nested():
       print 'Nested Catalog at:' , nested_catalog_ref.root_path
   print 'Listing repository'
   for full_path, dirent in repo:
       print full_path
