- * * debug: When set to true, it automatically set "auto_reload" to true as
- * well (default to false).
- *
- * * charset: The charset used by the templates (default to UTF-8).
- *
- * * base_template_class: The base template class to use for generated
- * templates (default to Twig_Template).
- *
- * * cache: An absolute path where to store the compiled templates,
- * a Twig_Cache_Interface implementation,
- * or false to disable compilation cache (default).
- *
- * * auto_reload: Whether to reload the template if the original source changed.
- * If you don't provide the auto_reload option, it will be
- * determined automatically based on the debug value.
- *
- * * strict_variables: Whether to ignore invalid variables in templates
- * (default to false).
- *
- * * autoescape: Whether to enable auto-escaping (default to html):
- * * false: disable auto-escaping
- * * true: equivalent to html
- * * html, js: set the autoescaping to one of the supported strategies
- * * name: set the autoescaping strategy based on the template name extension
- * * PHP callback: a PHP callback that returns an escaping strategy based on the template "name"
- *
- * * optimizations: A flag that indicates which optimizations to apply
- * (default to -1 which means that all optimizations are enabled;
- * set it to 0 to disable).
