# The following is the URL populated in /mirrors.txt as used by mirror://
# protocol scheme in sources.list
# the idea is that you can DNS rewrite 'mirrors.ubuntu.com' to this mirror
# and it will return a "list" of mirrors that includes only itself.
# then you can safely use something like the following in your sources.list
# and it will work with max speed on your own dns-rewritten lan and in the
# unmodified datacenter talking to the real mirrors.ubuntu.com:
#
# MURM="main universe restricted multiverse"
