-Toolbox module reorganization and more
---------------------------------------
-
-You can safely skip this section if this is your first encounter with MacPython.
-
-This release has a new organization of the mac-specific modules, and in
-general brings the MacPython folder structure more in line with
-unix-Python. This is not only a good idea, it will also immensely
-facilitate moving MacPython functionality to an OSX Python that is based
-on Mach-O and the unix-Python distribution. But don't worry: MacPython
-is definitely not dead yet, and the hope is that the transition will be
-as seamless as possible.
-
-First a change that should not cause too much concern: :Mac:Plugins has
-gone, and most of the dynamically loaded modules have moved to
-:Lib:lib-dynload.
-
-Second, and more important: the toolbox modules, such as Res and
-Resource, have moved to a Carbon package. So, in stead of "import Res"
-you should now say "from Carbon import Res" and in stead of "from Res
-import *" you should use "from Carbon.Res import *". For the lifetime of
-MacPython 2.2 there is a folder :Mac:Lib:lib-compat on sys.path that
-contains modules with the old names which imports the new names after
-issuing a warning.
-
-Note that although the package is called Carbon the modules work fine under
-classic PPC, and they are normal classic modules. Also note that some
-modules you may think of as toolbox modules (such as Waste) really are not,
-and they are not in the Carbon package.
-
-Also, all toolbox modules have been updated to Universal Headers 3.4, and
-are (for classic PPC) weak-linked against InterfaceLib so that they should
-work on all systems back to MacOS 8.1. Calling an unimplemented function will
-raise an exception, not crash your interpreter.
-  
-Another change related to the OSX growth path is that there is a new module
-macresource that you can use to easily open a resource file accompanying your
-script. Use "macresource.need("DLOG", MY_DIALOG_ID, "name.rsrc") and if the
-given resource is not available (it _is_ available if your script has been
-turned into an applet) the given resource file will be opened. This method will
-eventually also contain the magic needed to open the resource file on
-OSX MachO Python.
-
-Another feature to help with the OSX transition is that if you open a
-textfile for reading MacPython will now accept either unix linefeeds
-(LF, '\n') or Macintosh linefeeds (CR, '\r') and present both of them
-as '\n'. This is done on a low level, so it works for files opened by
-scripts as well as for your scripts and modules itself. This can be
-turned off with a preference/startup option.
-
-But:
-- this works only for input, and there's no way to find out what the original
-  linefeed convention of the file was.
-- Windows \r\n linefeeds are not supported and get turned into \n\n.
-- in 2.3 this feature will be replaced by a more general, platform independent
-  way of handling files with foreign newline conventions.

+Interaction with Mac OS X multiple users has been tested only very lightly.
