 '\"	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.
 '\"

 '\"	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

 '\"	the option's name in the option database, and dbClass gives
 '\"	the option's class in the option database.

 .SH NAME
 Tk_GetCapStyle, Tk_NameOfCapStyle \- translate between strings and cap styles
 .SH SYNOPSIS
 .nf
 \fB#include <tk.h>\fR
 .sp
 int
 \fBTk_GetCapStyle(\fIinterp, string, capPtr\fB)\fR
 .sp
 CONST char *
 \fBTk_NameOfCapStyle(\fIcap\fB)\fR
 .SH ARGUMENTS
 .AS "Tcl_Interp" *capPtr
 .AP Tcl_Interp *interp in
 Interpreter to use for error reporting.
 .AP "CONST char" *string in
 String containing name of cap style: one of ```butt'', ``projecting'',
 or ``round''.
 .AP int *capPtr out
 Pointer to location in which to store X cap style corresponding to
 \fIstring\fR.
 .AP int cap in
 Cap style: one of \fBCapButt\fR, \fBCapProjecting\fR, or \fBCapRound\fR.
 .BE

 .SH DESCRIPTION
 .PP
 \fBTk_GetCapStyle\fR places in \fI*capPtr\fR the X cap style
 corresponding to \fIstring\fR.
 This will be one of the values
 \fBCapButt\fR, \fBCapProjecting\fR, or \fBCapRound\fR.
 Cap styles are typically used in X graphics contexts to indicate
 how the end-points of lines should be capped.
 See the X documentation for information on what each style
 implies.
 .PP
 Under normal circumstances the return value is \fBTCL_OK\fR and
 \fIinterp\fR is unused.
 If \fIstring\fR doesn't contain a valid cap style
 or an abbreviation of one of these names, then an error message is
 stored in \fIinterp->result\fR, \fBTCL_ERROR\fR is returned, and
 \fI*capPtr\fR is unmodified.
 .PP
 \fBTk_NameOfCapStyle\fR is the logical inverse of \fBTk_GetCapStyle\fR.
 Given a cap style such as \fBCapButt\fR it returns a
 statically-allocated string corresponding to \fIcap\fR.
 If \fIcap\fR isn't a legal cap style, then
 ``unknown cap style'' is returned.
