command-line parsing code, splitting it up into several methods (new
methods: '_parse_command_opts()', '_show_help()') and making it put options
into the 'command_options' dictionary rather than instantiating command
objects and putting them there.

Lots of other little changes:
  * merged 'find_command_class()' and 'create_command_obj()' and
    called the result 'get_command_class()'
  * renamed 'find_command_obj()' to 'get_command_obj()', and added
    command object creation and maintenance of the command object cache to
    its responsibilities (taken over from 'create_command_obj()')
  * parse config files one-at-a-time, so we can keep track of the
    filename for later error reporting
  * tweaked some help messages
  * fixed up many obsolete comments and docstrings

is no index.htm[l] file, and when it is called, it also spits out the
headers.  When an index.htm[l] file is present, the regular (file
access) path is followed.  Also, when the guessed content-type matches
text/*, open the file in text mode; otherwise in binary mode.

destination path, otherwise show just the directory.

  objects, it now has method names.
Added three methods, 'has_lib()', 'has_scripts()', and 'has_data()'
  to determine if we need to run each of the three possible sub-commands.
Added 'get_sub_commands()' to take care of finding the methods named
  in 'sub_commands', running them, and interpreting the results to
  build a list of sub-commands that actually have to be run.

have any Python modules to install (rather than bomb when we try to copy
a non-existent directory).

implemented by subclasses, since they are needed by 'gen_lib_options()'.

and 'link_shared_lib()'.  In MSVCCompiler, this is meaningful: it adds
/EXPORT: options to the linker command line.  In UnixCCompiler, it
is ignored.

BeOS (up to 5.0) lacks <netinet/tcp.h>.

Blacklist HRDisposeReference and call it in the dispose routine.

Added some guiding comments.

(Completely uninspected and untested by me, this is just to
get the code into CVS!)

have to worry about "or []" in 'get_outputs()'.

'get_inputs()'.

new flexibility, specifically the 'root' option.  Now, we just use
"install" to do a fake installation into a temporary directory
(the 'bdist_dir' option, which derives from the 'bdist_base' option of
"bdist"), and then tar/zip up that directory.  This means that dumb
built distributions are now relative to the root directory, rather than
the prefix or exec-prefix; this is probably a feature, but does make
them slightly less flexible.

is more visible.

work yet, since the "build" command doesn't yet have a 'build_bdist'
option, and none of the "bdist" commands support it yet.)

(Is this really needed?  Can we drop it when the config file mechanism
allows users to set compiler flags in setup.cfg?)

the 'no_format_option' class attribute.
