-Buildroot is a set of Makefiles and patches that makes it easy to generate a

-system using the <a href= "http://www.uclibc.org/">uClibc C library</a>.
-Buildroot is useful mainly for people working with small or embedded
-systems.  Embedded systems often use processors that are not the regular
-x86 processors everyone is used to using on their PC. It can be PowerPC
-processors, MIPS processors, ARM processors, etc.  And to be extra safe,
-you do not need to be root to build or run Buildroot.

+<p>Buildroot is a set of Makefiles and patches that makes it easy to
+generate a complete embedded Linux system. Buildroot can generate any
+or all of a cross-compilation toolchain, a root filesystem, a kernel
+image and a bootloader image. Buildroot is useful mainly for people
+working with small or embedded systems, using various CPU
+architectures (x86, ARM, MIPS, PowerPC, etc.) : it automates the
+building process of your embedded system and eases the
+cross-compilation process.</p>
+
+<p>The major Buildroot features are:</p>
+
+<ul>
+
+  <li>Can <b>handle everything</b> in your embedded system development
+  project: cross-compiling toolchain, root filesystem generation,
+  kernel image compilation and bootloader compilation. Buildroot is
+  also sufficiently flexible that it can also be used for only one or
+  several of these steps.</li>
+
+  <li>Is <b>very easy</b> to set up, thanks to its menuconfig and
+  xconfig configuration interfaces, familiar to all embedded Linux
+  developers. Building a basic embedded Linux system with Buildroot
+  typically takes 15-30 minutes.</li>
+
+  <li>Supports <b>several hundreds of packages</b> for userspace
+  applications and libraries: X.org stack, Gtk2, Qt, DirectFB, SDL,
+  GStreamer and a large number of network-related and system-related
+  utilities and libraries are supported.</li>
+
+  <li>Supports <b>multiple filesystem types</b> for the root
+  filesystem image: JFFS2, UBIFS, tarballs, romfs, cramfs, squashfs
+  and more.</li>
+
+  <li>Can generate an uClibc cross-compilation toolchain, or re-use
+  your existing glibc, eglibc or uClibc cross-compilation
+  toolchain</li>
+
+  <li>Has a <b>simple structure</b> that makes it easy to understand
+  and extend. It relies only on the well-know Makefile language.</li>
+
+</ul>
