# Script to create a "release" subdirectory.  This is a subdirectory
# 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.

# We prune:
# - .svn subdirectories for obvious reasons.
# - contrib/gis/ and related files because it's huge and unneeded.
# - *.po and *.mo files because they are bulky and unneeded.
# - *.pyc and *.pyo because they aren't used by App Engine anyway.
