  =======================

  1. Requirements

     Make sure you have a SVr4 compatible Curses library installed.  If your
     vendor's Curses library is not of this type, then you have to install one
     of these free variants:

       - GNU NCurses, Version 4.2 or later
         ftp://ftp.clark.net/pub/dickey/ncurses/
         (works best, so this is recommended to use)

       - S-Lang, Version 1.0.2 or later
         ftp://space.mit.edu/pub/davis/slang/
         (works, but display is a little bit restricted)
     
     ATTENTION! The standard `old' BSD Curses library does _not_ work. So,
     under SunOS, HP-UX and other BSD-bases systems you really need GNU
     NCurses or S-Lang Curses installed. The modern BSD-variants like FreeBSD
     already have NCurses, of course.
     
  2. Configuring the source

     $ ./configure --prefix=/path/to/iselect
                  [--with-incdir=/path/to/{ncurses,slang}/include]
                  [--with-libdir=/path/to/{ncurses,slang}/lib]

  3. Build the program

     $ make

  4. Install the program and manpage as
     /path/to/iselect/bin/iselect
     /path/to/iselect/man/man1/iselect.1

     $ make install

  5. Cleanup

     $ make distclean
