-\fBmenu\fR - curses extension for programming menus
+\fBmenu\fR \- curses extension for programming menus
.SH SYNOPSIS
\fB#include <menu.h>\fR

.SH DESCRIPTION
The \fBmenu\fR library provides terminal-independent facilities for composing
-menu systems on character-cell terminals. The library includes: item routines,
+menu systems on character-cell terminals.
+The library includes: item routines,
which create and modify menu items; and menu routines, which group items into
menus, display menus on the screen, and handle interaction with the user.
-
+.PP
The \fBmenu\fR library uses the \fBcurses\fR libraries, and a curses
initialization routine such as \fBinitscr\fR must be called before using any of
-these functions. To use the \fBmenu\fR library, link with the options
-\fB-lmenu -lcurses\fR.

+these functions.
+To use the \fBmenu\fR library, link with the options
+\fB\-lmenu \-lcurses\fR.

+The \fBmenu\fR library maintains a default value for item attributes.
+You can
get or set this default by calling the appropriate \fBget_\fR or \fBset_\fR
-routine with a \fBNULL\fR item pointer. Changing this default with a
+routine with a \fBNULL\fR item pointer.
+Changing this default with a
\fBset_\fR function affects future item creations, but does not change the
rendering of items already created.

In your library list, libmenu.a should be before libncurses.a; that is,
-you want to say `-lmenu -lncurses', not the other way around (which would
-give you a link error using GNU \fBld\fR(1) and many other linkers).
+you should say \*(``\-lmenu \-lncurses\*('', not the other way around
+(which would give a link-error when using static libraries).
.SH PORTABILITY
