+Chameleon
+---------
+`Chameleon `_ Page Templates are an HTML/XML template
+engine implementation of the `Template Attribute Language (TAL) `_,
+`TAL Expression Syntax (TALES) `_,
+and `Macro Expansion TAL (Metal) ` syntaxes.
+
+Chameleon is available for Python 2.5 and up (including 3.x and pypy), and
+is commonly used by the `Pyramid Framework `_.
+
+Page Templates add within your document structure special element attributes
+and text markup. Using a set of simple language constructs, you control the
+document flow, element repetition, text replacement and translation. Because
+of the attribute-based syntax, unrendered page templates are valid HTML and can
+be viewed in a browser and even edited in WYSIWYG editors. This can make
+round-trip collaboration with designers and prototyping with static files in a
+browser easier.
+
+The basic TAL language is simple enough to grasp from an example:
+
+.. code-block:: html
+
+
+
+
Hello, World!
+
+
+
+
+
+
+
+
+
+
+
+The `` pattern for text insertion is common
+enough that if you do not require strict validity in your unrendered templates,
+you can replace it with a more terse and readable syntax that uses the pattern
+`${expression}`, as follows:
+
+.. code-block:: html
+
+
+
+
Hello, ${world}!
+
+
+
+ ${row.capitalize()} ${col}
+
+
+
+
+
+
+
+But keep in mind that the full `Default Text`
+syntax also allows for default content in the unrendered template.
