.SH NAME
\fB\%adacurses@USE_CFG_SUFFIX@\-config\fP \-
configuration helper for \fI@ADA_LIBNAME@\fP libraries

.SH DESCRIPTION
This program development aid simplifies the process of configuring
applications to use the \fI@ADA_LIBNAME@\fP library binding to
\fI\%ncurses\fP.
.SH OPTIONS
.TP 11 \" "--version" + 2n
\fB\-\-cflags\fP
reports the GNAT (Ada compiler) flags needed to compile with
\fI@ADA_LIBNAME@\fP.
.TP
\fB\-\-libs\fP
reports the GNAT libraries needed to link with \fI@ADA_LIBNAME@\fP.
.TP
\fB\-\-version\fP
reports the release and patch date information of the \fI\%ncurses\fP
libraries used to configure and build \fI@ADA_LIBNAME@\fP and exits
successfully.
.TP
\fB\-\-help\fP
issues a usage message and exits successfully.
.PP
Omitting options implies \*(``\fB\-\-cflags \-\-libs\fP\*(''.
.SH EXAMPLES
Consider a program using \fI@ADA_LIBNAME@\fP to write the message
\*(``Hello, world!\*('' in the center of the screen and wait for the
user to press the \*(``q\*('' key before exiting.
Populate a file \fIhello.adb\fP with the following.
.PP
.RS 4
.EX
with Terminal_Interface.Curses; use Terminal_Interface.Curses;

procedure Hello is
   Visibility : Cursor_Visibility := Invisible;
   Message : constant String := "Hello, World!";
   done : Boolean := False;
   c : Key_Code;
begin
   Init_Screen;
   Set_Echo_Mode (False);
   Set_Cursor_Visibility (Visibility);
   Set_Timeout_Mode (Standard_Window, Non_Blocking, 0);

   Move_Cursor (Line => Lines / 2,
                Column => (Columns \- Message\*'Length) / 2);
   Add (Str => Message);

   while not done loop
      c := Get_Keystroke (Standard_Window);

      case c is
          when Character\*'Pos (\*'q\*') => done := True;
          when others => null;
      end case;

      Nap_Milli_Seconds (50);
   end loop;
