-What is it?
-===========
-
-noice is a small curses-based file browser.
-It was first developed to be used with a TV remote control for a media
-center solution.
-
-
-Getting started
-===============
-
-Get the latest version from the git-repository; build and install it.  Run
-noice in a directory to display its content in the form of a list, where
-each line is a file or directory.  The currently selected item will be
-preceded with a " > " by default.
-
-For more information refer to the manpage.
-
-
-Building
-========
-
-To build noice you need a curses implementation available.  In most
-cases you just do:
-
-    make
-
-It is known to work on OpenBSD, NetBSD, FreeBSD, DragonFly BSD, Linux, OSX,
-IRIX 6.5, Haiku and Solaris 9.  Some notes for building on certain systems
-follow.
-
- * IRIX 6.5:
-   Tested with gcc from http://freeware.sgi.com/.
-
-    make CC="gcc" LDLIBS="-lgen -lcurses"
-
- * Haiku:
-
-    make LDLIBS="-lncurses"
-
- * Solaris 9:
-   Tested with gcc from http://www.opencsw.org/.
-
-    export PATH=/usr/ccs/bin:/opt/csw/bin:$PATH
-    make CC="gcc"
