Whats the big deal about FrameMaker?
FrameMaker is an industrial-strength desktop publishing package. Its designed for publishing book-level documents, and so is suited for technical writing. It has lots of high-level control, allows you to show or hide certain text based on conditions (useful for keeping text for two audiences in a single electronic file) and many other cool features. It seems to have become the de facto standard for print documentation. Its also designed so that the files it produces can be read by FrameMaker on other platforms, which makes it popular. I have clients who have Frame on UNIX and who have no trouble reading my Windows-produced files. I even used to exchange files between my Macintosh and a clients “Next” computer (remember those?).
