.SH NAME
\fBform\fR \- curses extension for programming forms
.SH SYNOPSIS

.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.

+Changing this default with a
\fBset_\fR function affects future field creations, but does not change the
rendering of fields already created.
