s3-package python scripts: easily manage large binary files in a git repo

pull-s3-package.py

#!/usr/bin/env python 
# 
#    This script reads packages from .s3. 
#    Given a directory, will pull all .s3 packages in it recursively.
#    Or, if you specify a .s3 file, it will pull just that package.

push-s3-package.py

#!/usr/bin/env python 
# 
#    Given a file, will md5 it, and upload it to s3. It will also generate a .s3 package file in the current dir.
#    If the specified name is a directory, it will tar it and gzip it, and store it so that it will be untarred.
#
#    Usage: push-s3-package myfile.tar.gz
#           push-s3-package mydir/
#    Naming convention for the resulting files is .s3:<md5>:<filename> OR .s3:dir:<md5>:<tarred filename>
#    The md5 in the second case is the md5 of the tar file.
