Bi-directional transformations

[Nathan Angelacos <nangel@...>]

Hi list,

Has anyone implemented something like boomerang 
(http://alliance.seas.upenn.edu/~harmony/) in lua?

alternatively, is anyone already working on or have bindings for augeas 
(http://www.augeas.net)

Thanks!
