You can compose topics by creating a topic outline file.
A topic outline file is an ASCII text file in a structured format that contains topic definitions. A topic outline file might appear as follows:
$Control:1 art <Accrue> *performing-arts <Accrue> **0.80 "ballet" **0.50 "drama" **0.50 ’dance’ **0.80 "opera" **0.80 "symphony" **0.90 "chamber music" **"Isaac Stern" *film <Accrue> **directors <Filter> /definition="title CONTAINS Truffaut" *visual-arts <Accrue> literature <Accrue> philosophy <Accrue> language <Accrue> history <Accrue> $$
You can create a topic outline file with any text editor.
