Use as follows:

1. Download casters: https://github.com/vivekpathak/casters
2. Use virtualenv as follows:

    virtualenv $(pwd)/env
    source env/bin/activate

3. Install couchdb

    pip install couchdb

4. Link casters to virtualenv

    ln -s path/to/casters-repo/casters.py env/bin/casters.py 

5. (Optionally) run CouchDB on a Docker container:

    docker run -d --name couchdb -p 5984:5984 -v ./couch_data:/usr/local/var/lib/couchdb:z klaemo/couchdb

6. Push to couchdb

    cd path/to/this/repo
    casters.py push http://admin:secret@localhost:5984/databasename/_design/simple

7. Done.

Additionally, _attachments should be a folder to put the statics (htmls and so on) but that will go on another repo, soon.
