Sorry, structure was probably a misleading word to use.  contrib is a 
directory in the top-level of the source tree.  It contains (amongst other 
things) a script called gcc_update.  This script will update a local copy 
of your cvs repository by doing a suitable sequence of "cvs update" 
commands.  The final part of the script will then touch certain 
autogenerated files such as gcc/configure to make sure that it is more 
recent than gcc/configure.in -- this avoids the need to continuously track 
tools such as autoconf to ensure that your copy is in sync with the copy 
used in the repository.

In summary, it's a shell script that does the right things to update the 
source for the tool you have checked out.
