It's a good idea to use the "Notify" option on this thread so you get informed when there's an update. As this is still very much a work-in-progress, you'll want to know. Details of updates will appear in the latest message in this thread, so go read it! 
Please refer to the included manual (Help->Contents) for instructions on use.
Pre-requisites:
For Windows, you will need Microsoft's .Net Framework 4 if you have not already got it, from this link on Microsoft's site:
http://www.microsoft.com/download/en/details.aspx?id=17851
For MacOSX and Linux, our tools may run under MONO.
You can download MONO from: http://www.go-mono.com/mono-downloads/download.html
Please read the documentation on the MONO site for how to install it and run programs using it. We do not provide support for how to use MONO. You should probably also read this thread as well:
