+PSP are expected to be its principle user group.

+Features:
+@enumerate
+@item Generates HTML, SGML, XML, SQL, Postscript, form email, LaTeX, or any other
+   text-based format.
+@item Cleanly separates content, graphic design, and program code.
+@item Blends the power and flexibility of Python with a simple template language
+   that non-programmers can understand.
+@item Gives template writers full access to any Python data structure, module,
+   function, object, or method in their templates.
+@item Makes code reuse easy by providing an object-orientated interface to
+   templates that is accessible from Python code or other Cheetah templates.
+   One template can subclass another and selectively reimplement sections of it.
+@item Provides a simple, yet powerful, caching mechanism that can dramatically
+   improve the performance of a dynamic website.
+@item Compiles templates into optimized, yet readable, Python code.
