If you are interested in finding out about all the features of the Developer Edition of Ruby In Steel, you might like to know that we've just put the help system online. This is a conversion into standard HTML of the integrated help system. We had to do a certain amount of hand editing to get the pages to display correctly (amongst other things, the help generator which we used for Visual Studio doesn't observe strict case-sensitivity which is required on our Linux-hosted web site). I'm hoping we ironed out most of the gremlins but if anyone spots any problems, please let me know. The help system has over 80 different topics. Remember that these all describe the Developer Edition so some features (such as the Cylon debugger and IntelliSense) do not apply to the free version.
