That's ok for the current string, due to it depends on Makefile rules.

BUCKET is a simple bucket name;
S3_BUCKET renamed to S3_BUCKET_URL to make it more informative.

Unfortunately AWS S3 doesn't have any command to create the directory.
The only way to create it is to copy recursively the empty one. So the
local empty directory is needed for it.
