This is a framework based on the Migrate API to ease building migrations
from one Drupal site to another. It is only supported at this time on Drupal 7
(i.e., Drupal 7 is the only destination). Besides addressing contemporary needs
to migrate to Drupal 7, it is intended to help serve as a proof-of-concept for
incorporating the migration approach into core as an upgrade path
(http://drupal.org/node/1052692).
This release addresses some minor bugs in the handling of language choices and adds overridable output through Drupal's theme layer. This was done to allow users to be able to quickly fix the fblikebutton via template files and preprocess functions in the event that FaceBook changes the expected structure of the iframe data.
