Packages will normally only move into the PRO area when a Program Library Release is performed.
Any new features relative to the previous release should be documented.
Certain packages, such as event generators, which are not maintained by the CN/ASD group, may move into PRO at the discretion of the CERN Program Librarian.
Routines that are in the PRO area should not generate any compilation warnings.
Testing of new releases should be performed both by the CERN Program Library team (the standard tests) and the developers (new features).
New or updated test procedures should be given to the CERN Program Library team as appropriate.
