     3  This file's random string on the first line is an optimization and
     4  paranoia facility for clients.
     5  
     6  If the client sees the same random string in multiple upload sessions,
     7  it assumes that the blobserver still has all the same blobs, and also
     8  it's the same server.  This mechanism is not fundamental to
     9  Camlistore's operation: the client could also check each blob before
    10  uploading, or enumerate all blobs from the server too.  This is purely
    11  an optimization so clients can mix this value into their "is this file
    12  uploaded?" local cache keys.
    13  
    14  If you deleted any blobs (or suspect any were corrupted), it's best to
    15  delete this file so clients can safely re-upload them.
