yann@815:       EGLIBC (Embedded GLIBC) is a variant of the standard GNU GLIBC
yann@815:       that is designed to work well on embedded systems.  EGLIBC strives
yann@815:       to be source and binary compatible with GLIBC.  Its goals include
yann@815:       a reduced footprint, configurable components, and improved
yann@815:       cross-compilation support.  EGLIBC also includes some embedded ports
yann@815:       (such as e500/spe) that are normally separate add-ons of GLIBC.

yann@710:       Please note:
yann@710:       - glibc has snapshots done every monday, and only the last ten are kept.

yann@710:       So if you want to be able to re-build your toolchain later, you will
yann@793:       have to save your C library tarball by yourself.
