such that if no traceback is passed
  and sys.exc_info() has been reset,
  the formatter just returns blank
  for the "traceback" portion.

- some long line cleanup

  where the source is stored temporarily is
  now made in the same directory as that of
  the .py file.  This ensures that the two
  files share the same filesystem, thus
  avoiding cross-filesystem synchronization
  issues.  Thanks to Charles Cazabon.

  line contains no line number, as in when
  inside an eval/exec-generated function.

  template.last_modified

  exc.__class__.__name__
  in html/text error templates when using
  Python 2.4 [ticket:131]

  template.get_def(...).render() now checks the
  argument signature the same way as it did in
  0.2.5, so that TypeError is not raised.

  a given path that is a directory, not a filename,
  instead of passing through to the template to
  generate IOError.  [ticket:73]

  is passed only an absolute filename (i.e. with c:
  drive etc.)  and no URI - the URI is converted
  to a forward-slash path and module_directory
  is treated as a windows path.  [ticket:128]

  uncommon feature, have been improved.  The defs
  no longer get doubly-rendered in the body() scope,
  and now allow local variable assignment without
  breakage.  [ticket:109]

  inheriting template - the full set of render()
  arguments are passed down through the inherits
  chain.  Undeclared arguments go into **pageargs
  as usual.  [ticket:116]

- finished cleanup for codegen.py, [ticket:98]

  non-whitespace character on a line by escaping
  it as in "%%". [ticket:112]

  text_error_template().render() now accept "error"
  and "traceback" as optional arguments, and
  these are now actually used.  [ticket:122]

- Python 3 support is added ! See README.py3k
  for installation and testing notes.
  [ticket:119]

- Source code escaping has been simplified.
  In particular, module source files are now
  generated with the Python "magic encoding
  comment", and source code is passed through
  mostly unescaped, except for that code which
  is regenerated from parsed Python source.
  This fixes usage of unicode in
  <%namespace:defname> tags.  [ticket:99]

  the base module.  [ticket:110]

  was causing tags to compile with
  case-insensitive names, thus messing up
  custom <%call> names. [ticket:108]

  to store templates, it uses the more
  permissive mode of 0775 instead of 0750,
  helping out with certain multi-process
  scenarios. Note that the mode is always
  subject to the restrictions of the existing
  umask. [ticket:101]

  AttributeError on attribute not found
  instead of RuntimeError.  [ticket:104]

  allows custom decoration functions to wrap
  rendering callables.  Mainly intended for
  custom caching algorithms, not sure what
  other uses there may be (but there may be).
  Examples are in the "filtering" docs.

  <%page> args named the same as a __builtin__ would not

  to be used in place of sys.exc_info()[2].  html_error_template()
  and text_error_template() accept an optional
  render()-time argument "traceback" which is passed to the
  RichTraceback object.
- lexer tests now rely upon an always-sorted dict repr()

  http://techspot.zzzeek.org/?p=28 has now
  been added as a built in syntax, and is recommended
  as a more modern syntax versus <%call expr="expression">.
  The %call tag itself will always remain,
  with <%namespacename:defname> presenting a more HTML-like
  alternative to calling defs, both plain and
  nested.  Many examples of the new syntax are in the
  "Calling a def with embedded content" section
  of the docs.

- added "cache_enabled=True" flag to Template,
  TemplateLookup.  Setting this to False causes cache
  operations to "pass through" and execute every time;
  this flag should be integrated in Pylons with its own
  cache_enabled configuration setting.

use Beaker 1.0.4, just checked in.   This version of Beaker stores
no persistent state in memory for each key, allowing dynamically
generated keys to work without using up available memory.

  e.g.  ${local.cache.get('somekey')} or
  template.cache.invalidate_body()

- the Cache object now supports invalidate_def(name),
  invalidate_body(), invalidate_closure(name),
  invalidate(key), which will remove the given key
  from the cache, if it exists.  The cache arguments
  (i.e. storage type) are derived from whatever has
  been already persisted for that template.

o remove the no longer needed Unicode/Str ast hack for Jython

adds support for Jython 2.5

fixes #90

- removed unnecessary attributes from DefTemplate.
- added ModuleTemplate class, which allows the construction
of a Template given a Python module generated by a previous
Template.   This allows Python modules alone to be used
as templates with no compilation step.   Source code
and template source are optional but allow error reporting
to work correctly.

container classes, so cache types such as
"ext:google", "ext:sqla", etc. are available.
memcached is available as both "ext:memcached" and
"memcached", the latter for backwards compatibility.
