Relevant reasoning of why by the author http://www.nico.schottelius.org/blog/migrating-away-from-pup...

I know it's not much of a big deal, but I have always been deterred from using Puppet, Chef, CfEngine because:

a) You need to setup a central server (I hate adding non-core infrastructure)

b) You need Ruby. IMHO a whole new world of dependencies to taint and un-simplify your precious production servers.

How do I get that README into a readable format? If the weird tags are part of github-flavoured markdown (I'm not familiar with it yet) then the appropriate extension should be added.
