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."
