"""
A small templating language

This implements a small templating language for use internally in
Paste and Paste Script.  This language implements if/elif/else,
for/continue/break, expressions, and blocks of Python code.  The
syntax is::

{{any expression (function calls etc)}}
  {{any expression | filter}}
  {{for x in y}}...{{endfor}}
  {{if x}}x{{elif y}}y{{else}}z{{endif}}
  {{py:x=1}}
  {{py:
  def foo(bar):
      return 'baz'
  }}
  {{default var = default_value}}
  {{# comment}}

You use this with the ``Template`` class or the ``sub`` shortcut.
The ``Template`` class takes the template string and the name of
the template (for errors) and a default namespace.  Then (like
``string.Template``) you can call the ``tmpl.substitute(**kw)``
method to make a substitution (or ``tmpl.substitute(a_dict)``).

``sub(content, **kw)`` substitutes the template immediately.  You
can use ``__name='tmpl.html'`` to set the name of the template.

If there are syntax errors ``TemplateError`` will be raised.
