+\fIValue\fR contains the text string to associate with \fIname\fR;
+this value will be returned in calls to \fBTk_GetOption\fR.
+\fIPriority\fR specifies the priority of the value; when options are
+queried using \fBTk_GetOption\fR, the value with the highest priority
+is returned.  \fIPriority\fR must be between 0 and TK_MAX_PRIO.  Some
+common priority values are:
+.TP
+20
+Used for default values hard-coded into widgets.

+\fB.Xdefaults\fR, resource databases loaded into the X server, or
+user-specific startup files.
