-IRB on a diet, for MacRuby / Ruby 1.9
+= IRB on a diet, for MacRuby / Ruby 1.9
+
+The goal is to have a small and cleaned up version of IRB. Trimmed down to only
+do the stuff I, and most people I know, actually use.
+
+Trimming down the core code is done mainly by using Ripper, which comes with
+Ruby 1.9, instead of shipping it's own parser etc.
+
+Furthermore, this IRB version specifically targets MacRuby, for now, and allows
+Cocoa development to be done from the command-line. Dietrb will automatically
+override the normal runloop to be ran in a thread and start a NSRunLoop on the
+main thread.
+
+There's still lots to be done, but the ‘basic functionality’ as is now, should
+not grow too much more. For now my things to-do are .irbrc support, completion,
+and investigate what else people really really need. After that it's time to
+polish.
