Tim's idea.)

storage.  Some of the internal operations have changed, coding style
is a bit less compact.  Other substantive changes include:

- The implementation now uses the CommitLog.PacklessLog temporary
  transaction log class.  This avoids the problem with tempfiles being
  unlinked as soon as they are created (and then lost if the process
  exits abnormally).

- Minimal is now derived from BerkeleyBase instead of Base.

- Some updates to use the latest PyBSDDB API, e.g. get() instead of
  has_key().

- The table names have changed to 'serials' and 'pickles'.

- tpc_vote() is now supported.  BerkeleyBase.tpc_vote() calls
  Minimal._vote() and this is where the commit log is placed into the
  promised state.

- The semantics are now that when the transaction successfully
  commits, the commit log file is deleted.  This may need to be
  changed to either a truncation-on-close, or scribble-zero-in-header
  approach for performance reasons.

and Minimal Berkeley storages.  It derives from
ZODB.BaseStorage.BaseStorage and supports the tpc_vote() method
wrapper calling _vote() on the derived class.

CommitLog.py -- contains the temporary transaction commit log file
classes used to hold transaction changes until they can be committed
to Berkeley.

test_commitlog.py tests creation, deletion, state transitions,
low-level and high-level APIs of the CommitLog and derived classes.

test_create.py tests creation of the Berkeley files when a storage is
created.

test_virgin.py tests that a newly minted Berkeley storage is empty,
and tests the first commits to such a new storage.

Correct an error in the output relating to implicit closure of <dt>
elements.

Revert an accidental re-indenting of a line that occurred in revision 1.8
that introduced a bug in the implicit closing of list- and table-related
elements.

Move all the test input/output files around so the test/ directory is
available for Zope-style regression tests; these will appear later.

the position info yet, though.

for consistency with nsgmllib and expat.

break the use from TALParser.

Repaired test for ""at most one of content, replace, repeat" TAL error
and improved the msg.

Update to reflect the new support for SGML declaration syntax.

.handle_decl():  Push SGML declarations into the instruction stream.

Change RuntimeError to SGMLParseError, which carries line number and
offset information.

Add support for SGML declaration syntax (<!....>) to some reasonable
degree.  This does not support everything allowed in SGML, but should
work with "real" HTML (internal subset in a DOCTYPE is not handled).
The content of the declaration is passed to the .handle_decl() method,
which can be overridden by subclasses.

Remove the do_text() method, this instruction is no longer used.

Also slightly refactored the starttag optimization code.
