You'll also see why Augment has a die-hard core of fans intent on moving it into the open-source world. Although Augment fully embraces mouse technology and the GUI, you drive it primarily with single-key commands. This may seem primitive compared with the nearly endless capabilities of Microsoft Word, but experienced Augment users will tell you that there's no faster or better way to create a structured, internally linked document that you and others can easily expand, edit, and link to other documents.
Two main efforts to breathe new life into Augment are under way; information about them is available at the HyperScope Wiki (blueoxen.net/c/hyperscope/wiki.pl?FrontPage) and at the OpenAugment Consortium (www.openaugment.org).
You can download OpenAugment from the latter site, but to run it you'll have to download a copy of Squeak—a multiplatform, open-source adaptation of Smalltalk-80, the language that did more than any other to codify object-oriented programming and extend object management to the graphical interface.
Carl Gundel produces Liberty Basic - the current version is done with VSE, but he's in the midst of a port to VisualWorks using Pollock.
