Most of the work hiding behind 'setup'
is really done within a Distribution instance, which farms the work out
to the Distutils commands specified on the command line.
Setup scripts will almost never instantiate Distribution directly,
unless the 'setup()' function is totally inadequate to their needs.
However, it is conceivable that a setup script might wish to subclass
Distribution for some specialized purpose, and then pass the subclass
to 'setup()' as the 'distclass' keyword argument. If so, it is
necessary to respect the expectations that 'setup' has of Distribution.
See the code for 'setup()', in core.py, for details.

attributes of a Distribution, and then use 'attrs' (a dictionary
mapping attribute names to values) to assign some of those
attributes their "real" values. (Any attributes not mentioned in
'attrs' will be assigned to some null value: 0, None, an empty list
or dictionary, etc.) Most importantly, initialize the
'command_obj' attribute to the empty dictionary; this will be
filled in with real command objects by 'parse_command_line()'.

a� Find as many configuration files as should be processed for this
platform, and return a list of filenames in the order in which they
should be parsed. The filenames returned are guaranteed to exist
(modulo nasty race conditions).
There are three possible config files: distutils.cfg in the
Distutils installation directory (ie. where the top-level
Distutils __inst__.py file lives), a file in the user's home
directory named .pydistutils.cfg on Unix and pydistutils.cfg
on Windows/Mac; and setup.cfg in the current directory.
The file in the user's home directory can be disabled with the
--no-user-cfg option.

S) a� Parse the setup script's command line, taken from the
'script_args' instance attribute (which defaults to 'sys.argv[1:]'
-- see 'setup()' in core.py). This list is first processed for
"global options" -- options that set attributes of the Distribution
instance. Then, it is alternately scanned for Distutils commands
and options for that command. Each new command terminates the
options for the previous command. The allowed options for a
command are determined by the 'user_options' attribute of the
command class -- thus, we have to be able to load command classes
in order to parse the command line. Any error in that 'options'
attribute raises DistutilsGetoptError; any error on the
command-line raises DistutilsArgError. If no Distutils commands
were found on the command line, raises DistutilsArgError. Return
true if command-line was successfully parsed and we should carry
on with executing commands; false if no errors but we shouldn't
execute commands (currently, this only happens if user asks for
help).

'parser' must be a FancyGetopt instance; 'args' must be the list
of arguments, starting with the current command (whose options
we are about to parse). Returns a new version of 'args' with
the next command at the front of the list; will be the empty
list if there are no more commands on the command line. Returns
None if the user asked for help on this command.

S) ab Show help for the setup script command-line in the form of
several lists of command-line options. 'parser' should be a
FancyGetopt instance; do not expect it to be returned in the
same state, as its option table will be reset to make it
generate the correct help text.
If 'global_options' is true, lists the global options:
--verbose, --dry-run, etc. If 'display_options' is true, lists
the "display-only" options: --name, --version, etc. Finally,
lists per-command help for every command name or command class
in 'commands'.

XqK XqK Wd S)ay Set the options for 'command_obj' from 'option_dict'. Basically
this means copying elements of a dictionary ('option_dict') to
attributes of an instance ('command').
'command_obj' must be a Command instance. If 'option_dict' is not
supplied, uses the standard option dictionary for this command
(from 'self.command_options').

| | � q� W| S)a� Reinitializes a command to the state it was in when first
returned by 'get_command_obj()': ie., initialized but not yet
finalized. This provides the opportunity to sneak option
values in programmatically, overriding or supplementing
user-supplied values from the config files and command line.
You'll have to re-finalize the command object (by calling
'finalize_options()' or 'ensure_finalized()') before using it for
real.
'command' should be a command name (string) or command object. If
'reinit_subcommands' is true, also reinitializes the command's
sub-commands, as declared by the 'sub_commands' class attribute (if
it has one). See the "install" command for an example. Only
reinitializes the sub-commands that actually matter, ie. those
whose test predicates return true.
Returns the reinitialized command object.
