SUMMARY = "C library for embedded systems" DESCRIPTION = "The name uClibc is an abbreviation for 'the \ microcontroller C library'. For simplicity, uClibc is pronounced \ 'yew-see-lib-see'. The goal of uClibc is to provide as much \ functionality as possible in a small amount of space, and it is intended \ primarily for embedded use. It is also highly configurable in supported \ features, at the cost of ABI differences for different configurations. \ uClibc has been designed from the ground up to be a C library for \ embedded Linux. It is NOT compatible with binaries linked against glibc."
