.SH NAME
-\fBform\fR - curses extension for programming forms
+\fBform\fR \- curses extension for programming forms
.SH SYNOPSIS
\fB#include <form.h>\fR
.br
.SH DESCRIPTION
The \fBform\fR library provides terminal-independent facilities for composing
-form screens on character-cell terminals. The library includes: field
+form screens on character-cell terminals.
+The library includes: field
routines, which create and modify form fields; and form routines, which group
fields into forms, display forms on the screen, and handle interaction with the
user.
.PP
-The \fBform\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 \fBform\fR library, link with the options
-\fB-lform -lcurses\fR.

+Your program should set up the locale, e.g.,
