# containing a bunch of symlinks, from which the app can be updated.

# The main reason for this is to import Django from a zipfile, which

# saves dramatically in upload time: statting and computing the SHA1

# for 1000s of files is slow.  Even if most of those files don't

# actually need to be uploaded, they still add to the work done for

# each update.
