eg: config.vm.provision 'shell', path: 'https://raw.githubusercontent.com/adlawson/vagrantfiles/mast...
I am a big fan of super simple provisioning for vagrant boxes. For development and trying new things a simple bash script has proven, in my experience, to be much less of a headache then chef etc.
If you'd like to contribute the changes or submit ideas that would be great. Don't worry if you can't or don't want to though!
I think that one of the most difficult barriers to trying out a new language is the initial setup. Some sites like golang.org and haskell.org let you play around on the homepage, but it isn't quite the same as having a working local environment.
Anyway, thanks for any support you may offer.
(Sometimes all you need is five lines of shell script to provision something, vs a full blown provisioning system and all the scaffolding that implies)
