can you spare some time?
i have this crazy thing with ruby.
when i enter irb and hit the return key, instead to run interactive
ruby the shell gives me this :
Directory doc already exists, but it looks like it
isn't an RDoc directory. Because RDoc doesn't want to risk
destroying any of your existing files, you'll need to
specify a different output directory name (using the
--op <dir> option).
any idea how to make irb work?
