really defined in distutils.dist and distutils.cmd."""

"""The gateway to the Distutils: do everything your setup script
|
|
needs to do, in a highly flexible and user-driven way. Briefly:
|
|
create a Distribution instance; parse the command-line, creating
|
|
and customizing instances of the command class for each command
|
|
found on the command-line; run each of those commands.
|
|
|
|
The Distribution instance might be an instance of a class
|
|
supplied via the 'distclass' keyword argument to 'setup'; if no
|
|
such class is supplied, then the 'Distribution' class (also in
|
|
this module) is instantiated. All other arguments to 'setup'
|
|
(except for 'cmdclass') are used to set attributes of the
|
|
Distribution instance.
|
|
|
|
The 'cmdclass' argument, if supplied, is a dictionary mapping
|
|
command names to command classes. Each command encountered on
|
|
the command line will be turned into a command class, which is in
|
|
turn instantiated; any class found in 'cmdclass' is used in place
|
|
of the default, which is (for command 'foo_bar') class 'foo_bar'
|
|
in module 'distutils.command.foo_bar'. The command class must
|
|
provide a 'user_options' attribute which is a list of option
|
|
specifiers for 'distutils.fancy_getopt'. Any command-line
|
|
options between the current and the next command are used to set
|
|
attributes of the current command object.
|
|
|
|
When the entire command-line has been successfully parsed, calls
|
|
the 'run()' method on each command object in turn. This method
|
|
will be driven entirely by the Distribution object (which each
|
|
command object has a reference to, thanks to its constructor),
|
|
and the command-specific options that became attributes of each
|
|
command object."""
