[Pythonmac-SIG] Status of Python 3.0 for Mac?

[Conan C. Albrecht]

You are all right in correcting me.  Here's a revised version of what  
to have to make multiple versions work:

If I type ls -l /usr/local/bin, I get the following in the list:

lrwxr-xr-x  1 root  wheel      72 Dec 16 10:05 python -> ../../../ 
Library/Frameworks/Python.framework/Versions/Current/bin/python
lrwxr-xr-x  1 root  wheel      71 Dec 16 10:05 pydoc -> ../../../ 
Library/Frameworks/Python.framework/Versions/Current/bin/pydoc
lrwxr-xr-x  1 root  wheel      79 Dec 16 10:05 python-config - 
 > ../../../Library/Frameworks/Python.framework/Versions/Current/bin/ 
python-config
lrwxr-xr-x  1 root  wheel      73 Dec 16 10:05 pythonw -> ../../../ 
Library/Frameworks/Python.framework/Versions/Current/bin/pythonw

Note that they all go to the "Current" version.  Then, in the /Library/ 
Frameworks/Python.framework/Versions directory, I have:

drwxrwxr-x  10 root  admin  340 Oct  1 17:52 2.6
drwxr-xr-x   9 root  admin  306 Dec  9 14:01 3.0
lrwxr-xr-x   1 root  admin    3 Dec 16 10:06 Current -> 2.6

Note that Current goes to 2.6.  To switch the "active" version of  
Python, just switch the symlink from 2.6 to 3.0.  That should switch  
the system.
