 =head2 Config File
 
 Instead of always using bulky command-line parameters, you can also
-use a config file in your home directory (C<~/.mytop>). If present,
-B<mytop> will read it automatically. It is read I<before> any of your

 command-line arguments are processed, so your command-line arguments
 will override directives in the config file.

 Here is a sample config file C<~/.mytop> which implements the defaults
 described above.
