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.

  around '=' sign in defs. [ticket:102]

  returns the time.time() when the module
  was created. [ticket:97]

workarounds; its AST matches CPython's pretty closely

  <%page> args named the same as a __builtin__ would not
  honor the default value specified in <%page> [ticket:93]

  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.
  [ticket:92]

and babel is responisble for stripping them when necessary
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.

a magic encoding comment

an expired section, instead of the original context
passed in [ticket:87]

a cached block would raise an error when called within a
cache-refresh operation that was initiated after the
initiating template had completed rendering.

this version (fixes incompatible compile symbols from 0.1
series).
- added a few docs for cache options, specifically those that
help with memcached.

render_unicode() from returning a unicode object

standard input as a template to stdout [ticket:81]
[ticket:56]

    names without explicit declaration (i.e. 'id',
    'exception', 'range', etc.) [ticket:83]

- some functions on Context are now private:
_push_buffer(), _pop_buffer(),
caller_stack._push_frame(), caller_stack._pop_frame().
- implemented [ticket:76] inlining of context.write()

  argument passed to Template or TemplateLookup.  All
  unicode-awareness and filtering is turned off, and template
  modules are generated with the appropriate magic encoding
  comment.  In this mode, template expressions can only
  receive raw bytestrings or Unicode objects which represent
  straight ASCII, and render_unicode() may not be used.
  [ticket:77]  (courtesy anonymous guest)

  directly to the %page or %def, i.e.
  <%def name="foo(x)" cached="True" cache_key="${x}"/>
  [ticket:78]

  more elaborate combinations of quotes and comments
  [ticket:75]

  configured as module level attributes, i.e. within
  <%! %> sections [ticket:62]
- removed reliance upon KeyError/AttributeError in namespace.__getattr__

  of html_error_template() to the buffered output

  blank exception pages when an inheriting template is
  present [ticket:71]

  caching, combined with an expression-based cache_key,
  combined with the usage of <%namespace import="*"/>

fixes #69

  with identifiers like "else", "finally", etc. inside them
  [ticket:68]

  did not have access to the correct context containing
  their 'self' and 'parent'

  incorrect "self" in the current context

  within a <%call> tag's argument list propigates 'caller'
  to the %call function itself (propigates to the inner
  calls too, this is a slight side effect which previously
  existed anyway)

exception reporter [ticket:51]

newlines in CRLF templates. follow up to #16.
