lorax/src/pylorax/output.py
Martin Gracik b672d9936e New version
Added support for Mako templates.
Changed the Lorax class to require an yumbase object as a parameter.
Changed a lot of unnecessary system calls to native python code.
Moved most of the file paths into a separate object.
The output and config objects are now singletons.
Also done a lot of code cleanup.
