FUNCTION
     function name

   * If invoked without argument, it displays rough usage of Asir.

   * If a function name is given and if there exists a file with the
     same name in the directory `help' under standard library directory,
     the file is displayed by a command set to the environmental
     variable `PAGER' or else command `more'.

   * If the `LANG' environment variable is set and its value begins
     with `"japan"' or `"ja_JP"', then the file in `help-jp' is
     displayed. If its value does not begin with `"japan"' or
     `"ja_JP"', then the file in `help-eg' is displayed.

   * On Windows HTML-style help is available from the menu.
