[ticket:129]

  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]

- cleanup

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

  % if: %endif, etc. [ticket:94]
- 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]

HTML file writing, consistently cleanup the modules/cache directories, use
nose skiptests for unsupported features.

  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.

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

fixes #100

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