          one-line descriptions are listed
  WHATIS  /B [options]

  /D [path]  Non-default path for whatis database location.
  /?         Shows the help.

Comments:

  This are FreeDOS clones of the Linux commands "apropos and whatis"
  APROPOS and WHATIS base their help on the lsm files stored in the 
  APPINFO directory.
  The first time it is run, APROPOS / WHATIS builds a database and stores 
  it in the help directory in the FreeDOS installation. This database can 
  be recreated by using:
    WHATIS /B

Examples:

  apropos edit  will display a list of editors
  apropos disk  will display a list of disk utilities
  whatis edit   will display a short information about edit
  whatis        will display a short information about the DOS commands
