documentation

"

    A model of a Smalltalk/X package in a checked-out working copy. 

    It knows how to map living classes to their respective file containers 

    and can fileout individual classes. Used (not only) by SCMAbstractCommitTask.

    == Changed packages ==

    A 'changed' package is a package that contain changes, i.e., some method/class

    beloging to a package has been modified or class/method has been added/removed.

    Compared to state of the package at its LOAD TIME, not to last nor compiled 

    revision !!!!!!

    See #hasChanges, #classesHasChanged, #extensionsHasChanged.
