is used in a wide variety of application domains.  Some of its key

introspection capabilities; intuitive object orientation; natural

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,

the web are actually aliases for @code{windows-1252}, and an @code{UTF-8}
or @code{UTF-16} BOM takes precedence over any other encoding declaration.
The WHATWG @url{https://encoding.spec.whatwg.org/,Encoding} standard
defines all such details so that implementations do not have to
reverse-engineer each other.

This module implements the Encoding standard and has encoding labels and
BOM detection, but the actual implementation for encoders and decoders

Pathlib offers a set of classes to handle file system paths.  It offers the
following advantages over using string objects:

@enumerate
@item No more cumbersome use of os and os.path functions.  Everything can
be done easily through operators, attribute accesses, and method calls.
@item Embodies the semantics of different path types.  For example,
comparing Windows paths ignores casing.
@item Well-defined semantics, eliminating any inconsistencies or
ambiguities (forward vs. backward slashes, etc.).

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.
