#  A small script to help upload cover art sets to CAA, for example
#  from VGMDB.  Put this script in a staging directory, which will
#  contain a subdirectory for each release you will be adding cover
#  art sets for.  Then copy or download all the cover art into the
#  staging directory and run this script with [a URL ending in] a
#  release MBID as an argument.
