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

97 Enter the date of the snapshot you want to use in the form: YYYYMMDD
98 where YYYY is the 4-digit year, MM the 2-digit month and DD the 2-digit
102 - glibc has snapshots done every monday, and only the last ten are kept.
103 - uClibc has daily snapshots, and only the last 30-or-so are kept.
105 So if you want to be able to re-build your toolchain later, you will
106 have to save your C library tarball by yourself.
