   4 # containing a bunch of symlinks, from which the app can be updated.
   5 # The main reason for this is to import Django from a zipfile, which
   6 # saves dramatically in upload time: statting and computing the SHA1
   7 # for 1000s of files is slow.  Even if most of those files don't
   8 # actually need to be uploaded, they still add to the work done for
   9 # each update.
