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

      A revision argument can be one of:
          NUMBER       revision number

      By default, when eglibc is downloaded it is checked out using
      svn://svn.eglibc.org. This option allows you to download eglibc
      from http://www.eglibc.org, if you are behind a proxy or firewall.
      If you are behind a proxy, don't forget to update your
      .subversion/servers file with your proxy info in [global].

      By default, the eglibc download will be an export of the subversion
      repository. If you say 'y' here, then the repository will instead be
      checked-out, so that you can update it later.
      
      Note that crosstool-NG will *not* update your working copy, you will
      have to do that yourself.
