 '\" The definitions below are for supplemental macros used in Tcl/Tk

 '\"
 '\" .AP type name in/out ?indent?
 '\"	Start paragraph describing an argument to a library procedure.
 '\"	type is type of argument (int, etc.), in/out is either "in", "out",
 '\"	or "in/out" to describe whether procedure reads or modifies arg,
 '\"	and indent is equivalent to second arg of .IP (shouldn't ever be
 '\"	needed;  use .AS below instead)
 '\"
 '\" .AS ?type? ?name?
 '\"	Give maximum sizes of arguments for setting tab stops.  Type and
 '\"	name are examples of largest possible arguments that will be passed
 '\"	to .AP later.  If args are omitted, default tab stops are used.
 '\"
 '\" .BS
 '\"	Start box enclosure.  From here until next .BE, everything will be
 '\"	enclosed in one large box.
 '\"
 '\" .BE
 '\"	End of box enclosure.

 '\"
 '\" .CE

 '\"
 '\" .VS ?version? ?br?
 '\"	Begin vertical sidebar, for use in marking newly-changed parts
 '\"	of man pages.  The first argument is ignored and used for recording
 '\"	the version when the .VS was added, so that the sidebars can be
 '\"	found and removed when they reach a certain age.  If another argument
 '\"	is present, then a line break is forced before starting the sidebar.

 '\"	by tabs.

 '\"
 '\" .OP cmdName dbName dbClass
 '\"	Start of description of a specific option.  cmdName gives the
 '\"	option's name as specified in the class command, dbName gives
 '\"	the option's name in the option database, and dbClass gives
 '\"	the option's class in the option database.

 .SH NAME
 Tk_AddOption \- Add an option to the option database
 .SH SYNOPSIS
 .nf
 \fB#include <tk.h>\fR
 .sp
 void
 \fBTk_AddOption\fR(\fItkwin, name, value, priority\fR)
 .SH ARGUMENTS
 .AP Tk_Window tkwin in
 Token for window.
 .AP "CONST char" *name in
 Multi-element name of option.
 .AP "CONST char" *value in
 Value of option.
 .AP int priority in
 Overall priority level to use for option.
 .BE

 .SH DESCRIPTION
 .PP
 This procedure is invoked to add an option to the database
 associated with \fItkwin\fR's main window.  \fIName\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 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.
 .TP
 40
 Used for options specified in application-specific startup files.
 .TP
 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
 80
 Used for options specified interactively after the application starts
 running.
