AWT - AbiWord Template
This is the format for AbiWord templates. Templates allow you to save sets of layouts, styles, and initial content that you use a lot. When you create a new document from a template, it applies that information from the template but changes are made to a new file, not to the template itself.
AbiWord is a free word processing program similar to Microsoft Word and is rapidly becoming a state of the art Word Processor. It has lots of features useful for your daily work, personal needs, or for just some good old typing fun.
