The whole context (from Learning OpenCV Computer Vision in C++ with the OpenCV Library (Early Release)):
Here are the current modules:
contrib: This module contains new things that have yet to be blessed into the whole of the library.
legacy: This module contains old things that have yet to be banished from the library altogether.
I can understand the sentence like "God bless you", but how to understand the code is blessed? who blessed the code? and what is the meaning of something blessed into something?
