This seems like it should be an easy thing to figure out, but I’ve been  
Googling for a half hour, plus looked in the Pickaxe book, but can’t  
seem to find an answer, so please forgive a really newbie-ish question,  
but…

How do you create a directory in Ruby? It appears to be via File.new,  
but I can’t figure out anything further than that.

Any help would be greatly appreciated.

TIA,  
Jeff

I’ve been using FileUtils.mkdir.
