if Python version is < 2.6 or is between 3.0 and
  less than 3.3, as Markupsafe now only supports 2.6->2.X,
  3.3->3.X. [ticket:216]

- clean up some list() calls we dont need

  setup.py instead of "install_requires".
  This to produce a lighter weight install
  for those who don't use the caching
  as well as to conform to Pyramid
  deployment practices.  [ticket:154]

  setup.py which prevented setup.py
  from running 2to3 on install.

  i.e. in place of cgi.escape().  Faster
  C-based implementation and also escapes
  single quotes for additional security.
  Supports the __html__ attribute for
  the given expression as well.

  When using "disable_unicode" mode,
  a pure Python HTML escaper function
  is used which also quotes single quotes.

  Note that Pylons by default doesn't
  use Mako's filter - check your
  environment.py file.

- 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]

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

- 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.

- 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.

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

- doc adjustments, changeset adjustments, modified unicode tests to
use ## instead of # for magic encoding comment.  # will still work for now.
- unsure whether we are going with #* *# or <%doc> for multiline comments,
looking like <%doc>.
