 .SH DESCRIPTION
 .PP
 The \fBoption\fR command allows you to add entries to the Tk option
 database or to retrieve options from the database.  The \fBadd\fR
 form of the command adds a new option to the database.
 \fIPattern\fR contains
 the option being specified, and consists of names and/or classes
 separated by asterisks or dots, in the usual X format.  \fIValue\fR
 contains a text string to associate with \fIpattern\fR;  this is the
 value that will be returned in calls to \fBTk_GetOption\fR or by
 invocations of the \fBoption get\fR command.  If \fIpriority\fR
 is specified, it indicates the priority level for this option (see
 below for legal values);  it defaults to \fBinteractive\fR.
 This command always returns an empty string.
 .PP
 The \fBoption clear\fR command clears the option database.  Default
 options (from the
 \fBRESOURCE_MANAGER\fR property or the \fB.Xdefaults\fR
 file) will be reloaded automatically the next time an
 option is added to the database or removed from it.  This command
 always returns an empty string.
 .PP
 The \fBoption get\fR command returns the value of the option
 specified for \fIwindow\fR
 under \fIname\fR and \fIclass\fR.  If several entries in the option
 database match \fIwindow\fR, \fIname\fR, and \fIclass\fR, then
 the command returns whichever was created with highest
 \fIpriority\fR level.  If there are several matching
 entries at the same priority level, then it returns whichever entry
 was most recently entered into the option database.  If there are
 no matching entries, then the empty string is returned.
 .PP
 The \fBreadfile\fR form of the command reads \fIfileName\fR,
 which should have the standard format for an
 X resource database such as \fB.Xdefaults\fR, and adds all the
 options specified in that file to the option database.  If \fIpriority\fR
 is specified, it indicates the priority level at which to enter the
 options;  \fIpriority\fR defaults to \fBinteractive\fR.
 .PP
 The \fIpriority\fR arguments to the \fBoption\fR command are
 normally specified symbolically using one of the following values:
 .TP
 \fBwidgetDefault\fR
 Level 20.  Used for default values hard-coded into widgets.
 .TP
 \fBstartupFile\fR
 Level 40.  Used for options specified in application-specific
 startup files.
 .TP
 \fBuserDefault\fR
 Level 60.  Used for options specified in user-specific defaults
 files, such as \fB.Xdefaults\fR, resource databases loaded into
 the X server, or user-specific startup files.
 .TP
 \fBinteractive\fR
 Level 80.  Used for options specified interactively after the application
 starts running.  If \fIpriority\fR isn't specified, it defaults to
 this level.
 .LP
 Any of the above keywords may be abbreviated.  In addition, priorities
 may be specified numerically using integers between 0 and 100,
 inclusive.  The numeric form is probably a bad idea except for new priority
 levels other than the ones given above.
