RHEL 6.3 veewee templates for vagrant use

These templates can be used to feed to veewee to spin up an el6 basebox for use with vagrant.

There are some coded values in definition.rb and ks.cfg which point at Yale-ishness. Amend to point at local RHEL iso/yum repo.

Built successfully with veewee 0.2.3, vagrant 1.0.3, Virtualbox 4.1.18.

;; Call the renderer-fn macro with a template and it returns a function optimized to render it.
;; This happens at compile-time. 
;; At run-time, you call this function with the parameters that will be interpolated into the template,
;; typically (but not limited to) a map.
;;
;; Useful in i18n for variable interpolation, for example. I'm using this to add internationalization
;; support to https://github.com/xavi/noir-auth-app

Properties

From the built-in help system:

For many settings TextMate will look for a .tm_properties file in the current folder and in any parent folders (up to the user’s home folder).

These are simple setting = value listings where the value is a format string in which other variables can be referenced.
