[Zope3-checkins] CVS: Zope3/src/zope/event/tests - __init__.py:1.2 subscriber.py:1.2 test_eventchannel.py:1.2

[Jim Fulton]

Update of /cvs-repository/Zope3/src/zope/event/tests
In directory cvs.zope.org:/tmp/cvs-serv15352/src/zope/event/tests

Added Files:
	__init__.py subscriber.py test_eventchannel.py 
Log Message:
Grand renaming:

- Renamed most files (especially python modules) to lower case.

- Moved views and interfaces into separate hierarchies within each
  project, where each top-level directory under the zope package
  is a separate project.

- Moved everything to src from lib/python.

  lib/python will eventually go away. I need access to the cvs
  repository to make this happen, however.

There are probably some bits that are broken. All tests pass
and zope runs, but I haven't tried everything. There are a number
of cleanups I'll work on tomorrow.
