Using a single original document set to generate dead tree and on-line documentation, and usually also on-line help. In practice, it most often refers to a FrameMaker file set with conditional text which, when the conditions are set appropriately, allows you to create variants of the original document (e.g., for a product that runs on different Unixplatforms) as well as for different media -- typically task-oriented on-line help to be accessed under Microsoft Windows or from a web browser, linear printed document, and HTML delivered via the WWW and/or CD-ROM.
