cdlibrary console is a python package installable by any of the following commands: command line:

cd cdlibrary; python setup.py install
easy_install cdlibrary
easy_install http://hg.codeflow.org/cdlibrary/archive/tip.tar.gz

Once you have the package installed (as root) you need to add a daemon script: command line:

sudo su -
wget http://hg.codeflow.org/cdlibrary/archive/tip.tar.gz
tar xzvf tip.tar.gz
cp cdlibrary-*/cdlibd /etc/init.d
update-rc.d -f cdlibd defaults

you can also use the code below as a start script: code:

import sys
from cdlibrary import http, filesystem

daemon = filesystem.daemon
#daemon = http.daemon

if __name__ == '__main__':
    command = sys.argv[1]
    if command == 'start':
    elif command == 'stop':
    elif command ==  'restart':
    elif command == 'debug':


command line:

/etc/init.d/cdlibd start|stop|restart|debug
