OSS projects for accessing data held in .pst format

Thanks to Neil Jefferies for a link to this article in The Register, which tells us that MS has begun two open source projects that will make it possible for developers to create tools to 'browse, read and extract emails, calendar, contacts and events information' which live in MS Outlook's .pst file format. These tools are the PST Data Structure View Tool and the PST File Format SDK, and both are to be Apache-licensed.
