When started on &prog; will potentially look in 5 different places for files
to examine for configuration information.  &prog; reads from the locations in
order, so the user can override the default options.  Note that on Macintosh
and Windows systems the "current directory" mentioned below is the directory
where the &prog; application has been installed.

The standard &prog; options are read first.  On UNIX this file is in the file
<LITERAL>etc/options</LITERAL> in the &prog; distribution directory.  Changing
that file will change the options settings for all users.  On Macintosh and
Windows system the standard options are stored in the &prog; application
itself and can't be changed (easily).
