Tips on what this document could include:
o Find a pointer to the list of Ibiblio mirrors
o Give an example command line for at least rsync, wget and curl where the two last ones will use ftp
o Give an example cron expression and /etc/cron.d/ file that's useful for making a mirrors including setting the correct permissions
o Give an example Apache configuration on how to configure Apache to serve the mirror
This document should possibly be a part of http://maven.apache.org/guides/mini/guide-mirror-settings.html
The command to create a mirror is
rsync -v -t -l -r ftp.ibiblio.org::maven2 /your/local/path
