  == About Buildroot
  
  Buildroot is a tool that simplifies and automates the process of
  building a complete Linux system for an embedded system, using
  cross-compilation.
  
  In order to achieve this, Buildroot is able to generate a
  cross-compilation toolchain, a root filesystem, a Linux kernel image
  and a bootloader for your target. Buildroot can be used for any
  combination of these options, independently (you can for example use
  an existing cross-compilation toolchain, and build only your root
  filesystem with Buildroot).
  
  Buildroot is useful mainly for people working with embedded systems.
  Embedded systems often use processors that are not the regular x86
  processors everyone is used to having in his PC. They can be PowerPC
  processors, MIPS processors, ARM processors, etc.
  
  Buildroot supports numerous processors and their variants; it also
  comes with default configurations for several boards available
  off-the-shelf. Besides this, a number of third-party projects are based on,
  or develop their BSP footnote:[BSP: Board Support Package] or
  SDK footnote:[SDK: Software Development Kit] on top of Buildroot.
