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. iÿÿÿÿN(tescape(tquote(tloopert TemplateErrortTemplatetsubt HTMLTemplatetsub_htmlthtmltbunchs \{\{|\}\}s\s+in\s+s^[a-z_][a-z0-9_]*$cBs#eZdZdd„Zd„ZRS(s.Exception raised while parsing a template cCs||_||_||_dS(N(tmessagetpositiontname(tselfR R R ((s=/usr/local/lib/python2.7/dist-packages/paste/util/template.pyt__init__3s  cCsEd|j|jd|jdf}|jrA|d|j7}n|S(Ns%s at line %s column %siis in %s(R R R (R tmsg((s=/usr/local/lib/python2.7/dist-packages/paste/util/template.pyt__str__8s !
