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