Uploading patches on a webpage is hard. Command line uploading is the future!
The script requires Python 2.6. If this is a terrible burden for you, let me know.
STATIC_DEPS=true pip install -e git://github.com/jbalogh/bzattach.git#egg=bzattach
If you want to make the script suck less, check out the source and run
STATIC_DEPS=true pip install reqs.txt
If you're not installing this in a virtualenv you're crazy.
The STATIC_DEPS=true part may not be necessary on non-Mac systems.
