Coil is a configuration language, inspired by some of SmartFrog's features (http://www.hpl.hp.com/research/smartfrog/papers.htm), aimed at Python programs in general and Twisted in particular. Coil will at some point become twisted.coil and form the basis for a new (but, of course, completely optional) deployment system for Twisted.
You can download it at: http://itamarst.org/software/coil-0.1.tar.gz
and read the documentation (also in the tarball) at: http://svn.twistedmatrix.com/cvs/sandbox/itamar/coil/DOC.txt?view=auto&r...
I forgot to add a license file, but it's licensed under same terms as Twisted itself (i.e. MIT license).
Coil's development was sponsored by my employer, ITA Software (we're hiring: http://www.itasoftware.com/careers/)
