-A small templating language
-
-This implements a small templating language. 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.
