Description:

DO NOT DIRECTLY REFER TO THIS CLASS OR USE IT OTHERWISE IN YOUR CODE:

This is a dummy, mimicry class to allow some squeak code to be filed in.
Its protocol is neither complete, nor fully compatible with the corresponding
squeak original class.
ALSO: be aware, that this PackageInfo class does not know much about how ST/X
organizes its extensions. So NEVER EVER think about using it to get pacakgeInfo
on ST/X packages. It is only present to support porting Squeak tools, which
read Squeak packages (i.e. code importer packages).
One such being the monticello framework.

Class protocol:

 default

 initialize

cg: the allSbclassesDo may be expensive;

 allPackages

returns the monticello packages

usage example(s):

self allPackages

 named: aString

 registerPackageName: aString

 existPackageNamed: aString

self existPackageNamed: 'PackageInfo'
self existPackageNamed: 'Zork'

Instance protocol:

 name: something

 = other

 hash

(comment from inherited method)
return an Integer useful as a hash key for the receiver.
This hash should return same values for objects with same
contents (i.e. use this to hash on structure)
