Usage: tools/dev/retab.rb directory will retab with 2-width spaces rather than tabs for indentation. This utility should be used by the @tabassassin account when it's unleashed on the Metasploit code base in order to make git blame a little easier to spot. (diffs should use -b or -w to avoid seeing @tabassassin's changes)
