     "Python is a remarkably powerful dynamic programming language that
is used in a wide variety of application domains.  Some of its key
distinguishing features include: clear, readable syntax; strong
introspection capabilities; intuitive object orientation; natural
expression of procedural code; full modularity, supporting hierarchical
packages; exception-based error handling; and very high level dynamic
data types.")

EmPy can expand arbitrary Python expressions and statements in this way, as
well as a variety of special forms.  Textual data not explicitly delimited in
this way is sent unaffected to the output, allowing Python to be used in
effect as a markup language.  Also supported are callbacks via hooks,
recording and playback via diversions, and dynamic, chainable filters.  The
system is highly configurable via command line options and embedded
commands.")

    (description
     "Natsort lets you apply natural sorting on lists instead of
lexicographical.  If you use the built-in @code{sorted} method in python
on a list such as @code{['a20', 'a9', 'a1', 'a4', 'a10']}, it would be
returned as @code{['a1', 'a10', 'a20', 'a4', 'a9']}.  Natsort provides a
function @code{natsorted} that identifies numbers and sorts them separately
from strings.  It can also sort version numbers, real numbers, mixed types
and more, and comes with a shell command @command{natsort} that exposes this
functionality in the command line.")

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:
@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.

C++ types in Python and vice versa, mainly to create Python bindings of
existing C++ code.  Its goals and syntax are similar to the excellent
Boost.Python library by David Abrahams: to minimize boilerplate code in
traditional extension modules by inferring type information using compile-time
introspection.")
