+Creating a new Distutils command
+================================
+
+This section outlines the steps to create a new Distutils command.
+
+A new command lives in a module in the :mod:`distutils.command` package. There
+is a sample template in that directory called :file:`command_template`.  Copy
+this file to a new module with the same name as the new command you're
+implementing.  This module should implement a class with the same name as the
+module (and the command).  So, for instance, to create the command
+``peel_banana`` (so that users can run ``setup.py peel_banana``), you'd copy
+:file:`command_template` to :file:`distutils/command/peel_banana.py`, then edit
+it so that it's implementing the class :class:`peel_banana`, a subclass of
+:class:`distutils.cmd.Command`.
+
+Subclasses of :class:`Command` must define the following methods.
+
+.. method:: Command.initialize_options()
+
+   Set default values for all the options that this command supports.  Note that
+   these defaults may be overridden by other commands, by the setup script, by
+   config files, or by the command-line.  Thus, this is not the place to code
+   dependencies between options; generally, :meth:`initialize_options`
+   implementations are just a bunch of ``self.foo = None`` assignments.
+
+
+.. method:: Command.finalize_options()
+
+   Set final values for all the options that this command supports. This is
+   always called as late as possible, ie.  after any option assignments from the
+   command-line or from other commands have been done.  Thus, this is the place
+   to to code option dependencies: if *foo* depends on *bar*, then it is safe to
+   set *foo* from *bar* as long as *foo* still has the same value it was
+   assigned in :meth:`initialize_options`.
+
+
+.. method:: Command.run()
+
+   A command's raison d'etre: carry out the action it exists to perform, controlled
+   by the options initialized in :meth:`initialize_options`, customized by other
+   commands, the setup script, the command-line, and config files, and finalized in
+   :meth:`finalize_options`.  All terminal output and filesystem interaction should
+   be done by :meth:`run`.
+
+
+.. attribute:: Command.sub_commands
+
+   *sub_commands* formalizes the notion of a "family" of commands,
+   e.g. ``install`` as the parent with sub-commands ``install_lib``,
+   ``install_headers``, etc.  The parent of a family of commands defines
+   *sub_commands* as a class attribute; it's a list of 2-tuples ``(command_name,
+   predicate)``, with *command_name* a string and *predicate* a function, a
+   string or ``None``.  *predicate* is a method of the parent command that
+   determines whether the corresponding command is applicable in the current
+   situation.  (E.g. we ``install_headers`` is only applicable if we have any C
+   header files to install.)  If *predicate* is ``None``, that command is always
+   applicable.
+
+   *sub_commands* is usually defined at the *end* of a class, because
+   predicates can be methods of the class, so they must already have been
+   defined.  The canonical example is the :command:`install` command.
