Hi folks,
today I found myself wanting to get the parent directory name of a file, so I 
was looking whether Pathname has an to_a so I could do:

parent_dir = path.to_a[-2]

Since it didn't exist, I've written a small patch against CVS to add this 
simple function, maybe you find it useful :-)

C'ya,
	Marc
