MacPorts 2.0.0-beta1 now available for testing

[Michael_google gmail_Gersten]

>From the changelog:

83	    - Port images are now stored as archives. Archive mode is now effectively
84	      always on. Among other benefits, this fixes some bugs with the handling
85	      of hard links installed by ports (e.g. #13601).
86	
87	      Direct mode is no longer available. Existing port image
directories, and
88	      installed files for direct mode, will be converted to archives when
89	      upgrading.

What is archive mode?
