Get rid of a bunch of completed or cancelled to-do items.  This really
isn't an accurate reflection of the long-term direction of PEAK any more,
so it really needs more work.  But for now I might as well remove the
done's and the definite won't-do's.

Added 'ref:factory@addr' URL scheme that maps to a corresponding
'naming.Reference("factory",["addr"])'.  'factory' can be either a dotted
import string referencing a 'naming.IObjectFactory', or you can define
a factory in the 'peak.naming.factories' property space.

Added a 'zconfig.schema' factory, so that 'ref:zconfig.schema@streamURL'
will load a schema loader.  See CHANGES.txt for more details on all the
cool stuff you can do with this.

Renamed old 'ddt.web' to 'ddt.view', and added new 'ddt.web' that publishes
a directory of test documents.  So, using::

    peak ddt.web src/peak/ddt/tests

would display a list of test documents in your browser, letting you click
on the documents to run the tests and display the results.

Added '[Named Services]' section parser to 'peak.ini'.  This new section
type functions almost identically to '[Component Factories]', except that
the keys are property names rather than references to interfaces or other
component keys.  This should be helpful for configuring shared services
that all implement the same interface, such as SQL connection objects.

Note that to look up a named service, you simply use the appropriate
property name, as usual.  The difference is that you are guaranteed to
always use the same *instance* of the service, within a given service
area.

Also, added 'ddt.SQLChecker()', which verifies SQL results against a
test document.  'SQLChecker' makes use of the new "Named Services" feature
in order to ensure it's accessing the database you intend to test (as
opposed to say, the nearest SQL connection object).

Added rough draft of 'RowProcessor'.  Expanded 'ICellMapper' interface to
cover new needs, and refactored mapper implementations to inherit from a
common base for most of their methods.  Added 'Score.__nonzero__' method,
so that you can use 'if cell.score:' to tell whether a cell has already
been marked.

Major upgrades to DDT package:

* Added 'ICellMapper' interface to allow introspective actions on objects,
  with adapters predefined for methods, properties, and 'model.IFeature'
  objects.

* Added 'MethodProcessor' and 'ModelProcessor' (test), and
  'ActionProcessor' (not yet tested)

* Lots and lots of docstrings added

* The 'HTMLDocument' DM now always strips leading/trailing whitespace from
  cell text.

* New functions 'ddt.titleAsMethodName()' and 'ddt.titleAsPropertyName()'
  for standardized parsing of certain types of cell data.

* Updated demo classes to use both 'MethodProcessor' and 'ModelProcessor'

* Fixed 'Cell.assertEqual()' to normalize its input value to the same type
  that it's interpreting the cell as.  This effectively allows the fallthru
  comparison case to be 'str(value)==cell.text', when the "official" type
  for the cell is unknown.

* Fix 'ddt.web' runner to work properly when serving a single file as the
  root.  (We probably also need some way for this to support a convenient
  run-once-and-exit strategy.)

Implemented boolean operations on 'events.IConditional' objects, and added
'isTrue' and 'isFalse' event sources to 'IValue' objects.  So now you can
do things like 'yield aCondition & otherCondition' to wait until two
conditions are true.  Unfortunately, it is possible to have a race
condition if some code sets 'aCondition' to true before setting
'otherCondition' to false, in that as soon as both are true, the waiting
thread would resume.  Sometimes this is what you want, and sometimes not.
I'm beginning to wonder if one needs a sort of "transactionality" to
events, so that one can set a variety of values or conditions, and *then*
allow the callbacks to fire.  But that will require some further thought.

Made better distinctions between Value and Condition behaviors, and added
ability to easily adapt from one to the other.  Added 'events.subscribe()'
to allow automatic re-subscription to a source, with automatic or manual
cancellation (automatic happens if the subscriber goes away).  Revised
derived values and all types of conditions to work via delegation rather
than inheritance, making use of 'events.subscribe()'.  We're now in a lot
better shape for adding logical operations on conditions and making
it easier to derive conditions or values from other conditions or values.

Big migration to 'peak.events': 'UntwistedReactor' and 'MainLoop' are now
just facades over 'EventLoop'.  Added untested Twisted support to implement
'peak.events' interfaces as facades over a reactor.  Minor interface tweaks
in 'peak.events' to cover the needs of real (and testable) event loops.
Moved 'ifTwisted' and 'makeTwisted' to 'peak.events.api'.  Ported
'TaskQueue' and 'FastCGIAcceptor' to use threads for scheduling.  Por

Other: fixed 'commands.AbstractInterpreter' failing with usage errors at
construction time, rather than at use time.  Refactored 'CGIInterpreter' to
be an actual interpreter, and 'CGICommand' to not run an event loop unless
FastCGI is being used.  Also changed 'CGICommand' to perform setup at _run
time rather than immediately upon assembly.

Lots of 'peak.events' migration:

Added 'events.ISignalSource', that returns 'events.Broadcaster' objects for
signals.  This allows you to yield to signals in an 'events.Thread', or
safely set one-time callbacks on them.

'running.ISignalManager' is now DEPRECATED; please use
'events.ISignalSource' instead.

'running.IMainLoop' has been changed to use an 'events.IReadable' for
the 'lastActivity' attribute, and the 'setExitCode' and 'childForked'
methods have been replaced with an 'exitWith()' method.

The 'peak.running.mainLoop.signalHandler' property has been replaced with
'peak.running.mainLoop.stopOnSignals', which defaults to including SIGINT,
SIGTERM, and SIGBREAK.  If you need custom signal handling, please use
the event sources provided by an 'events.ISignalSource'.

'peak.running.process.ChildProcess' has been rewritten to use
'events.ISignalSource' and an 'events.Thread' to monitor SIGCHLD.  Removed
'checkStatus()' from the 'running.IProcessProxy' interface.

Made most event sources weak-referenceable.

Changed 'events.Thread' to keep a reference to an object it's yielding on,
so that "weak" events like signals and I/O events will hang around until
they call back to the thread.

"csv" and "csv.<dialect_name>" cursor formaters using csv module.

Issues:
- end-of-line character handling. Right now n2 output redirection always
  gets you text mode. force csv line terminator to "\n" so you get local
  newlines for now. But what about binary output formats? Do we need
  some kind of binary-mode redirection operators?
- dialect defaults for delimiter, etc are not overrideable by n2's go
  command line options. (problem? should "go -m csv -d "\t" work the
  same as "go -m csv.excel-tab"?)
- csv.py not installed by setup.py? (haven't looked into it yet)

First pass of 'logs' framework refactoring.  Highlights include:

 * Lots of new unit tests for logging.

 * Logs are now accessed via a 'logs.ILoggingService' instance.  The
   'logger:' URL scheme automatically accesses the nearest such service.
   For backward compatibility, the old 'peak.logs' namespace is still used
   to supply the actual loggers.  This will be gradually replaced with a
   plugin-based mechanism.

 * Log events don't use a positional 'message' argument any more, and
   loggers aren't responsible for interpolating message arguments any more.
   The new signature is 'Event(parent, msg=msg, args=args, ...)'.  Loggers
   also now tell events what logger name they are, via the 'ident' keyword.

 * The logging system now uses a property namespace, 'peak.logging.levels',
   to obtain log level names and values.  The various 'logs.LEVEL'
   constants are now DEPRECATED.  Please use the 'getLevelFor()' method of
   the nearest 'logs.ILoggingService' instead.  URL schemes such as
   'logfile:' also no longer convert their level names to numbers, since
   the level names are only meaningful in the context of a logging service.

 * Support for integration with the Python 2.3/PEP 282 logging module has
   been scaled back.  There are too many globalisms and dependencies there.
   When we add plugin-based log configuration, it should be possible to use
   the logging package's handlers and formatters with the PEAK logging
   services.  At that point, you'll be able to replace 'logging.getLogger'
   and 'logging.getLevelName' with the corresponding methods of a PEAK
   logging service, if you need to force non-PEAK packages to use PEAK's
   logging.

 * 'config.Namespace()' objects now have a 'keys()' method that can be used
   when the namespace is bound to a context component.  It returns a list
   of strings that may be used as keys for that namespace.  See
   'CHANGES.txt' for an example.

Plugins have landed!

* Added 'binding.PluginKeys' and 'binding.PluginsFor'.  These are component
  keys that can be used to 'Obtain' plugins registered within a property
  namespace.  'PluginKeys' obtains a list of the plugins' configuration
  keys, while 'PluginsFor' obtains a list of the actual plugins.

* Replaced 'peak.config.registries.EigenRegistry' with
  'peak.config.registries.ImmutableConfig'.  The only use we had for
  'EigenRegistry' was to keep track of 'offerAs' settings within classes,
  and it didn't need all the extra complexity of eigenstate management.
  The new, more-specialized class is shorter, simpler, and easier to use.

MAJOR API REFACTORING for 'peak.config', to support iterating over
configuration keys, 'n2' navigability of properties, and much more.
Many APIs are now DEPRECATED or renamed; please see CHANGES.txt for
a complete description.  A few highlights:

 - 'config.lookup()' replaces 'findUtility' and 'getProperty'

 - 'config.iterValues()' replaces 'findUtilities'

 - 'config.iterKeys()' finds keys in a specific namespace

 - NEW: 'config.parentProviding()' and 'config.parentsProviding()'
   APIs to find parent components that support a protocol.

 - NEW: You can now use 'peak n2 config:' to explore the default
   property namespace.  For example 'ls -l peak.naming.schemes'
   will list all defined naming schemes.

Please see CHANGES.txt for the list of deprecated or removed APIs.

Added 'config.MultiKey()' and 'config.UnionOf()' configuration key classes,
to generalize existing specialty keys such as 'ProviderOf' and
'FactoryFor'.  (The latter two are now defined in terms of the former
two.)  Also, made classes and types usable as configuration keys.  This
was needed for the above generalization, but also makes many other
class-lookup concepts possible.  (Note that there may be some slight
changes to the effective registration and lookup order of these and other
configuration keys as of this change, as there were some previous errors
and/or ambiguities to the lookup order that were not covered by the test
suite.)

Finished out timer service with wildcard 'addListener()' support, and a
'timer:foo.bar' URL scheme, so you can now 'Obtain("timer:myapp.whatever")'
in your applications.  Of course, to be really useful, we need some
listeners that can log or otherwise output the statistics.  And I'm still
planning to move the time-critical parts of the Timer class to Pyrex.  But
the timing framework itself is now complete and ready-to-use.

Significant refactoring of skin/layer/resource/interaction/service classes
in 'peak.web'.  Primary goal was to allow layers to be shared between
skins, but several other things were also accomplished:

 * Got rid of properties to configure services and factories, using
   "[Component Factories]" mechanism instead.

 * Added explicit interfaces for auth/skin/layer/resource services

 * Interaction and InteractionPolicy implement various services by
   delegation, so things like 'interaction.skin.getResource()' are
   now 'interaction.getResource()' and 'policy.skinSvc.getSkin()'
   is now 'policy.getSkin()', etc.

 * Cleaned up various "spaghetti bindings" that wandered all over the
   place.

 * Added 'IInteractionPolicy.newInteraction()' for cleaner creation of
   interaction instances.

 * Added layer service mechanism to allow layers to be reused among skins.
   Layers are defined in the 'peak.web.layers' property namespace.

 * Added skin service mechanism that locates skins using
   'interaction.skinName' (which defaults to '"default"').  Skins are
   defined in the 'peak.web.skins' property namespace.

 * Simplified 'config.CreateViaFactory' to allow factories with
   no arguments.

Fixed 'text' DOMlet not XML-quoting output.  Added 'xml' DOMlet for
outputting already-quoted output.  Added 'notag', 'text.notag', and
'xml.notag' variants that throw away their opening/closing tags.  'notag'
does nothing except throw away the open/close tags, which is useful when
'pwt:define'-ing a block that has multiple elements in it, among other
things.  With 'text.notag' or 'xml.notag', you can now embed text in other
text without needing to keep the "span" in the output.

Logging-related interfaces have been moved into the 'peak.running.logs'
module.  So, what used to be 'running.ILogger' is now 'logs.ILogger'.

Log events now use a standard component construction signature, and the
class used for event objects is now configurable as the factory for
'logs.ILogEvent'.  (See "Component Factories" in 'peak.ini'.)

By popular demand, 'logs.ILogger' (and its default implementation) now
includes 'trace()', 'notice()', 'alert()' and 'emergency()' methods that
use the corresponding 'syslog' priority levels.  'logs.IBasicLogger' has
been added, to reflect the narrower interface provided by PEP 282, and
there is an adapter that can extend PEP 282 loggers with the other methods.

Finally, added 'logs.ILoggingService' (for future implementation), and
updated TODO to reflect short-term project priorities that take precedence
over the alpha 3 release for now.

only "core" API packages and primitives, not the full set of available
framework APIs.  'peak.api' will continue to expand as frameworks are
added, but 'peak.core' will stay as small as practical.  ('peak.exceptions'
may in fact end up being removed from 'peak.core', or at least renamed.)

Also, added 'peak.util.symbol' module, to contain 'NOT_GIVEN', 'NOT_FOUND',
and the 'Symbol' class used to create them.

Note that the new 'Make' and 'Obtain' bindings also support sequences of
recipes and keys, and in those cases will produce a sequence of the results
from those recipes or keys.  Also, 'Make' will accept no-argument and
one-argument callables,  where 'Once' always required three-argument
functions.  This should make it a lot easier to write short binding
functions.

Also, note that the 'activateUponAssembly' keyword is now 'uponAssembly',
and 'isVolatile' is now 'noCache'.  (The old names will work as keyword
arguments until the alpha 4 development cycle begins.)  The
'binding.IActiveDescriptor' interface also changed as a result of this.
Last, but not least, a 'binding.IRecipe' interface was added, to support
the new 'binding.Make' type.

'naming.IBasicContext.lookup()' and 'naming.lookup()' now accept a 'default'
argument, similar to that used by 'lookupComponent()' and most other
lookup-like APIs in PEAK.  This change was made so that component lookups
don't need to rely on catching 'exceptions.NameNotFound' errors to tell them
when to use the default value.  This could hide 'NameNotFound' errors that
were actually from a broken component somewhere in the lookup process.  (In
general, it's probably a bad idea to have an exception that's used for both
control flow and real errors!)

Also, removed most trapping of 'NameNotFound' errors throughout PEAK,
except for those in N2, which I'll leave for Ty.  :)  Last, but not least,
cleaned up documentation of related interfaces/methods.

general networking-related features that don't really fit into storage,
naming, etc.

Also, an icb protocol implementation work-in-progress.  ICB ("Internet
CB") is an ancient chat protocol that's not widely used anymore except
in some circles.  This is more of an example than something likely to be
useful by many people, but I have a use for it. Still needs work, though.

There is now an interface for "Active Descriptors":

The naming system base classes no longer use 'attrs' as an input parameter
or return value. If you've subclassed anything from 'peak.naming.contexts',
note that your '_get()' methods should now just return the lookup value,
rather than a 'state,attrs' tuple.  For most naming contexts, this just
means you should change 'return foo, None' statements to just 'return foo'.

All 'peak.binding' APIs now only accept positional parameters for items
unique to that API.  Items common to multiple APIs (such as 'offerAs',
'doc', 'attrName', etc.) should now be supplied as keyword arguments.

Bindings also now automatically "suggest" the containing object as a parent
component for the contained object, whenever a value is assigned to them or
computed.  If a non-None 'adaptTo' is set on the binding, the value assigned
or computed will be adapted to the specified protocol before the parent
component is suggested.  'binding.New()' no longer relies on the
'IComponentFactory' interface, but instead uses the new adapt/suggest
mechanisms.

Previously, parent components were only "suggested" when a binding was set
via component constructor keyword arguments.  Now, this is done at any time
bindings are set, but *not* for non-binding keyword arguments.  In other
words, ordinary attributes of a component do not receive "suggested parent"
notices, even when set via constructor keyword arguments.  If you want an
attribute to do this, you must define the attribute with the binding API;
e.g. via 'requireBinding()' or 'binding.Constant()'.

Added a ZConfig schema for 'running.commands.EventDriven' applications,
a ZConfig component definition for adaptive tasks, and a running shortcut
called 'EventDriven'.  It should now be possible to do this::

     #!/usr/bin/env peak EventDriven

at the top of a ZConfig file formatted according to the new schema, and
have it run.  Unfortunately, so far the only type of task that can be
included is 'running.daemons.AdaptiveTask', which doesn't actually *do*
anything.  So, right now doing this is equivalent to creating an over-
engineered 'sleep' command.  ;)

Also, fixed a problem in ZConfig 'schema.dtd'; I used 'PCDATA' where I
should've used 'CDATA', and I fixed various problems with the
'fromZConfig()' component constructor.  It's kind of annoying that ZConfig
defaults unspecified items to 'None', even if you said they weren't
required and had no default. :(  I'll see if I can do something about this
later; for now I just delete 'None' values from the data.

we have some meaningful schemas and configurations to test with.  There
is a 'zconfig.schema' URL scheme that loads a command interpreter, and
a 'peak ZConfig' option as well.  See 'CHANGES.txt' for details on the new
features.  Also, fixed up some issues with the 'fromZConfig()' component
constructor.  All we need now are some useful base schemas for daemons,
and the last piece for 0.5a2 (besides PyProtocols) will be in place.

Began the move of 'peak.interface' to a separate 'protocols' package for
ease of distribution independently of PEAK.  Also, removed caching of
success/failed adapter lookups, because there was no way for them to be
cleared when declarations were made for base classes of a class whose
lookup was cached.  (To do caching, I'll have to add a separate cache.)

In the next pass, I'll add the new declaration API that Ty and I designed,
and then change PEAK to use it, factoring out the interim API, and changing
the few remaining introspections in PEAK to work via adapation.  Then, it's
off to documentation, unit tests, and packaging for the 'protocols'
package.

First draft implementation of system scheduling proposal.  (Also, misc.
TODO additions.) Interfaces have been streamlined and names changed.
Daemons are now "periodic tasks", and the provided base class implements an
"adaptive task" interface.  "Daemonic app", "event loop", and "daemon
scheduler" are now just a single "system scheduler" interface, which can
schedule periodic tasks as well as one-offs.  I settled on "higher priority
number" = "higher priority" for priority sorting.

I'm beginning to like this whole "asynchronous programming" model that
Twisted provides.  AdaptiveTask (formerly BaseDaemon) is a lot simpler,
MultiDaemon went away, and the system scheduler is only two screens
of code to manage idle timeouts, prioritized task scheduling, and more.
Heck, "shutdown after X" was as simple as 'callLater(duration,self.stop)'!

There is one minor problem in this draft...  if a task raises an unhandled
exception, it won't be scheduled for further re-run.  I'm not sure if this
is a bug or feature yet.  It should be easy to fix, though.

REINSTALL WARNING: a package was removed from setup.py on this change,
so be sure to *delete* your PEAK installation from 'site-packages' before
reinstalling.  Also be sure to update your checkout with 'cvs update -dPA'.

Change notes:

* It's now possible to use 'config.declareModule()' to patch third-party
  (i.e. non-PEAK) modules, and also to pre-declare inheritance or patch
  data for modules inherited via package inheritance.  This was done to
  make PEAK/Zope reusage/patching easier, and also to ease patching of
  large generated-code models (like UML and CWM).

* The patches to add "Pythonic features" to UML models are now in a
  separate module, 'peak.metamodels.core_addons', so that they can be
  shared amongst all UML versions.  This was made possible by the
  new 'declareModule()' function.

* Cleaned up and removed the now-unnecessary subpackage of UML13 that was
  there just to provide a home for the patches that can now be applied by
  "remote control", so to speak.

* 'lazyModule()' now has an extra parameter that can be used to hook the
  initial loading of a module.  This was added so that 'declareModule()'
  can patch modules when they are loaded.

arguments (name and value) and returns a replacement value.  The value

Otherwise, it's a list of values returned from the LDAP directory (except
for the 'dn' field, which is always just a string.)  Converters are
imported from within the peak.storage package, so we can add some
"standard" converters and then reference them with import strings
like '"LDAP.someConverter"'.

SQL error handling and joinTxn() shortcut

* SQL errors are now logged; __traceback_info__ is set, although our
  current traceback formatter for logging doesn't use it yet.  We also
  maybe should log SQL warnings at LOG_WARNING level instead of LOG_ERROR.

* You can now supply joinTxn=(a true value) as a keyword arg to a SQL
  query executed on an SQLConnection, and the connection will join the
  transaction.  This seems cleaner in actual use than a separate .joinTxn()
  call.

* Fixed some issues with Gadlfy not implementing the full DBAPI - or even
  a decent fraction of it.  :(

PropertyName -> peak.api; Improved lazy import facility

* naming.PropertyName is now simply PropertyName; it never really had much
  to do with naming in the first place, doesn't depend on anything else,
  and needs to be accessible in all major subpackages and in end-user API
  calls.  So now it's in-line in the peak.api module.

* Added a 'lazyModule(moduleName)' function to peak.util.imports.  This
  new "next generation" way of creating a lazily-loaded module actually
  creates an object that *will be* the real module in sys.modules, and once
  loaded will be indistinguishable from an ordinary Python module.  (Well,
  under Python 2.3 the type() will be different, but you can't have
  everything.)  I was getting really fed up of tracing into
  lazyImport.__getattr__ during debugging sessions, so I was inspired to
  come up with something that would only have code overhead when it's first
  touched.  Subclassing ModuleType, adding a __getattribute__ method, and
  clever use of the Python 'reload()' function saved the day.

* This now completes all the non-documentation items I want for 0.5a1,
  although I may "work ahead" a little on the features list, especially if
  Ty keeps pressing for SQL type maps and LDAP schemas.  ;)  (In truth, I'd
  like those and some of the other database features Real Soon Now myself.)

Components now support names and paths:

* Objects created by naming system lookup, binding.New(), or
  AutoCreated, can all now automatically receive information
  about their name as well as their parent component.

* binding.getComponentName() gets an object's name or 'None'

* binding.getComponentPath(c, relativeTo=None) gets an object's
  path from its root component, or as a relative path from
  'relativeTo' (assumes 'relativeTo' is a parent of 'c').
  Unknown names are rendered as '*' in the path.

* Added 'binding.Acquire' after all.

* Improved management of _p_jar/_p_oid by model.Element, using
  _p_jar as the parent component, and _p_oid as the component
  name for elements.

* Added unit tests for name and path support.

Reorgs and and misc. cleanups; updated TODO for 0.5a1 vs 0.5final

Moved ActiveDescriptor(s) classes from binding.meta to binding.once and the
rest of binding.meta to model.method_exporter.  Moved the method-exporter
tests that lived in metamodels.tests.General to model.tests, where they
really belonged, and added model.tests to the install and API test suite.

Reformatted peak.running.clusters docstring to structured text for better
HappyDoc output.  Defined the rule for 'peak.running.cluster._filename' in
peak.ini instead of in the code.

Renamed PropSet to PropertySet, and made it possible to go from a
PropertyName to a PropertySet by calling '.of()' (e.g.
'PropertyName("foo").of(anObj)'.  PropertySets can now reproduce in various
ways, e.g.:

     c = PropertyName('peak.running.cluster').of(None) # -> PropertySet

     c._host['two.baz.com']	# ('even','prime','weird')
     c._groups()		# ('odd','even','prime','weird','qux')

But none of this is documented yet and possibly subject to change.  :)
(Especially since we're probably going to change how the cluster namespace
works anyhow!)

Ideally, it should be easy to go from a property name to its value or to
a property set, and to go from a property set to a value in some namespace.
Of course, it's somewhat questionable whether we'll be doing this for that
many properties in the first place!  And this is all going to go "full
circle" once properties have a naming context that can be used to look
them up in.  I worry a bit about creeping TMTOWTDI-ism in all this.  :(

Reverted the ability to omit schemes/bodies from parsed URLs, since that
might violate the IName interface contract for URLs!  Fixed a problem with
_defaultScheme support.  Made some notes in TODO about issues in the naming
system that need review/investigation.

Made peak.model StructuralFeatures use a uniform API for manipulating
object attributes, which will make it easier to implement "lazy load"
attributes later, and made it easier to implement _p_change support, which
was also added.  IBindingAPI now includes _getBinding, _setBinding,
_delBinding, and _hasBinding methods, and model.Element sets _p_changed
when a modifier method is called.  Also did some more TODO reprioritizing;
it now reflects the 0.5 priority order much better, even though it still
lumps items together by package.

* Added 'binding.Constant(key, value)', which allows you to specify
  a constant value to be used as a property or utility in that
  component subtree.

* Added storage.get/begin/commit/abortTransaction() APIs for ease
  of use in short scripts.  Defined a default provider for
  ITransactionService in peak.ini that provides each component root
  with its own TransactionService instance.  It's easily replaceable
  with other allocation strategies, if it should be needed.  I may
  change this later to a per-root strategy, since the current strategy
  requires creating localConfigs for each component root.  We'll see
  what actual use has to say about the best way of doing it.

* Fixed a problem with local/global config object startup that could
  cause "phantom" configuration objects to appear via recursion of
  getLocal() or getGlobal().

* Got rid of binding.meta.assertInterfaces, which is no longer needed
  because the Interface package now correctly handles metaclass
  instances.

* Got rid of Singleton, since it's not used for anything and I could
  neither think of any use cases nor remember why I added it in the
  first place!

* Made it possible for CachingProviders to cache per-localConfig as well
  as per-object.  This is handy for implementing per-hierarchy services,
  like the TransactionService provider mentioned above.

* Misc. TODO updates.

Made Model.Element Persistent.  There is still an unresolved issue relating
to mixing Persistent with other metaclasses under Python 2.2, however.  Be
wary of mixing Persistent with *any* PEAK class until it's fixed.  :(

Re-org/refactoring of many items from the TODO list for 0.5, including:

* moved peak.binding.imports -> peak.util.imports, added importSuite()

* Decided not to do binding.Acquire, it should just be a documented idiom

* Moved LDAP and lockfile URLs to peak.storage.LDAP and
  peak.running.lockfiles, respectively

* Moved factories.getObjectInstance -> spi, updated peak.ini to load
  naming.spi as the provider.

* Consolidated naming.references into naming.names

* Made ParsedURLs compile their pattern strings, and automatically make
  their 'fromX()' methods classmethods (and the same is true for other
  'struct' types.

* Refactored cursors and connections out into distinct SQLCursor/LDAPCursor
  types, based on a common AbstractCursor.

* Added TooManyResults/TooFewResults errors to peak.exceptions

Completed configuration files refactoring.  Configuration files now can
have [Load Settings From] and [Provide Utilities] sections, and property
sections can now define rules instead of just values.  Property values are
eval()'d at rule access time rather than configuration loading time, and
they have access to 'propertyMap', 'propertyName', and 'targetObj' locals,
as well as the full peak.api.* and config_components' globals.  "Load
Settings From" sections can access a potentially infinite variety of
sources for loading configuration data; the sources are defined using
the 'peak.config.loaders.*' property namespace, and thus can be
meta-configured even in the same configuration file.  Builtin loader types
are 'file' and 'mapping'.  GlobalConfig no longer has any hard-wired
configuration steps; everything is now in the peak.ini file.  Subclasses
of GlobalConfig need only perform 'self.config_filenames.append(fname)'
before calling GlobalConfig's 'setup()' method, to cause additional config
files to be loaded after 'peak.ini'.

Everything that is configurable in PEAK, is now (in principle) configurable
via property files.

A first pass at cleaning up the TODO file.  Also, removed the Specialist
class and associated interfaces altogether, since Racks can serve all the
same functions in PEAK.  (Perhaps Rack should be renamed to Specialist, but
