buildroot: making Embedded Linux easy
Buildroot is a set of Makefiles and patches that makes it easy generate a cross-compilation toolchain and root filesystem for your target Linux system using the uClibc C library. 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.
