I suggest being more verbose here. Maybe use the text from Debian:

*
**text-based template engine and Python code generator*

Cheetah can be used as a standalone templating utility or referenced as
a library from other Python applications. It has many potential uses,
but web developers looking for a viable alternative to ASP, JSP, PHP and
PSP are expected to be its principle user group.

Features:

 * Generates HTML, SGML, XML, SQL, Postscript, form email, LaTeX, or any other
   text-based format.
 * Cleanly separates content, graphic design, and program code.
 * Blends the power and flexibility of Python with a simple template language
   that non-programmers can understand.
 * Gives template writers full access to any Python data structure, module,
   function, object, or method in their templates.
 * 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.
 * Provides a simple, yet powerful, caching mechanism that can dramatically
   improve the performance of a dynamic website.
 * Compiles templates into optimized, yet readable, Python code.


Otherwise LGTM.

Is only Python 2 supported?

This site doesn't load for me.

I agree with Hartmut's suggestion.

> +    (license license:expat)))

This license appears to be a unique creation of the Cheetah authors. I
recommend using 'x11-style'.

Unfortunately yes. See also https://pythonhosted.org/Cheetah/roadmap.html .

Huh. Strange, it doesn't for me either.

Maybe we should better use https://pythonhosted.org/Cheetah/ .
