        This port is kept up with the IT++ GIT 'master' branch, which is typically updated daily to weekly.  This version of IT++ generally contains fixes to, and its API is compatible with, the current IT++ release, and will be incorporated in an upcoming release. This port may or not compile or function correctly, as it represents a work in progress. If it does not work, check back in a few days. Or try deactivating the currently active IT++ port, cleaning any current builds, and trying again.
