commit 8c335bde7192512b038f7d7c06ca5bf43f27f1e4 Author: Radek Pazdera rpazdera@redhat.com Date: Mon Jul 30 12:21:13 2012 +0200

misc: Adding recipe_conv script

misc directory was created to store things related to LNST, which doesn't fit into any other existing directory.

recipe_conv.py was added to the directory right away. It's a helper script, that will convert any unsupported features found in recipes to their supported equivalents.
