DESCRIPTION
       The  option command allows you to add entries to the Ck option database
       or to retrieve options from the database.  The add form of the  command
       adds  a	new option to the database.  Pattern contains the option being
       specified, and consists of names and/or classes separated by  asterisks
       or  dots, in the usual X format.	 Value contains a text string to asso-
       ciate with pattern;  this is the value that will be returned in invoca-
       tions  of  the  option get command.  If priority is specified, it indi-
       cates the priority level for this option (see below for legal  values);
       it  defaults  to	 interactive.	This  command  always returns an empty
       string.

       The option clear command clears the option database. This  command  al-
       ways returns an empty string.

       The  option  get	 command returns the value of the option specified for
       window under name and class.  If several entries in the option database
       match  window,  name, and class, then the command returns whichever was
       created with highest priority level.  If there are several matching en-
       tries  at  the same priority level, then it returns whichever entry was
       most recently entered into the option database.	If there are no match-
       ing entries, then the empty string is returned.

       The  readfile form of the command reads fileName, which should have the
       standard format for an X resource database such as .Xdefaults, and adds
       all the options specified in that file to the option database.  If pri-
       ority is specified, it indicates the priority level at which  to	 enter
       the options;  priority defaults to interactive.

       The  priority  arguments	 to  the option command are normally specified
       symbolically using one of the following values:

       widgetDefault
	      Level 20.	 Used for default values hard-coded into widgets.

       startupFile
	      Level 40.	 Used for options  specified  in  application-specific
	      startup files.

       userDefault
	      Level  60.  Used for options specified in user-specific defaults
	      files, such as .Xdefaults, resource databases loaded into the  X
	      server, or user-specific startup files.

       interactive
	      Level  80.   Used	 for options specified interactively after the
	      application starts running.  If priority isn't specified, it de-
	      faults to this level.

       Any  of the above keywords may be abbreviated.  In addition, priorities
       may be specified numerically using integers between 0 and  100,	inclu-
       sive.   The numeric form is probably a bad idea except for new priority
       levels other than the ones given above.
