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

- img: another imaging package. Has more file format support and is faster
than imaging, but has only limited operations on images. There is a bridge
between the packages.
- Numeric: the LLNL Numeric Python extension. All sorts of nifty operations
on matrices and such. This is the most recent version from the sourceforge archive.
Numeric has moved from Extensions to :Lib:site-python, by the way, see the release
notes.

After the installer finishes it automatically launches the appropriate

Carbon versions of Python by running either ConfigurePythonClassic or ConfigurePythonCarbon.

Moving your Python installation after installing is generally not a good idea.
If you have to do this anyway you should remove your preference file, run
ConfigurePython and remove all .pyc files. (there's a script zappyc.py that does
the latter).

you have no internet connection. Please also read the Relnotes file for
