Playground for writing a tool that analyzes a ZODB storage for missing
classes and allows to `touch` object records that reference a class from
an indirect import.
snapshot of some work
Restructure, fix copyright, add entry point for creating executable.
- Rename classes to factories
- Handle factories which don't know their name gracefully, but provide a
  warning.
- Only log progress message every 5k objects.
Add boilerplate for tests.

Remove references to private code from buildout.
Write test for missing factory reference.

Rename test file so the runner picks it up.
Add simple case of rewriting: rename a class within its module.
Provide tests for the case where __name__ is missing due to a factory being
registered with copy_reg.

Provide special  case where __module__ is missing (seems to be the case for
Zope 2's Missing.Value object). Still looking for a simple test case, though.
Document that I just can't get a test case for this issue.
Silence logging output during test runs.
Clean up output, provide more options.
Release-preparation: licensing, documentation
Release metadata cleanup, documentation wording.
Move from sandbox into main repository area.
Move back: forgot to create trunk
Second try: move project out of sandbox
Post-release cleanup.
Started working on code that allows modifying pickles directly.
cleanup, refactoring
Snapshot: add tests for pickle rewriting from genops stream, use symbolic
names instead of string constants, clean up some refactoring mess.
