   I will recommend using Yaouh! or the other one that I've forgotten the
name of, search for "command line yaouh clone" in the archives. But that
should not be allowed to ruin the fun of working it out on the command line:

   Shorter (and likely faster) using awk, xargs and wget:

$ (cd ~/Maps/OSM && find -type f -print | cut -c3- | \
awk ' { print "http://tile.openstreetmap.org/" $0; }' | \
xargs wget --force-directories --no-host-directories -N --user-agent 'Opera')

-N doesn't do what you hope it does, but it has the important side effect of
making wget overwrite existing files instead of creating file.1.

   Figuring out what needs to be done to obviate the need for
--no-host-directories is left as an excercise to the reader.
