I have a simple 2 node cluster (master on one, workers on both). I tried using: python disco/util/distrfiles.py bigtxt /etc/nodes > bigtxt.chunks To distribute the files (which worked ok).

Right way to create [self]respawning app in python
I am using jabber bot written in python to log some MUC talks. Sometimes it drops on some network or XMPP problems. In this case I have to start it again by myself.

What to put in a python module docstring?
Ok, so I've read both PEP 8 and PEP 257, and I've written lots of docstrings for functions and classes, but I'm a little unsure about what should go in a module docstring.
