Hi Xavier,

It might be as easy as this:

for TILE in `find /path/to/tiles -type f`; do
 echo "${TILE}"
 FILE=`basename "${TILE}"`
 L1=`dirname "${TILE}" | gawk -F"/" '{ print $NF}'`
 L2=`dirname "${TILE}" | gawk -F"/" '{ print $(NF-1)}'`
 curl --output "${TILE}"

curl and http are on the same line, you mail program might split in over
two lines.

Kind regards,
