Search for playlists, and move them all into an import directory.

#! /bin/bash

# This is a script I'm using to copy m3u playlist files from my music library into an import directory for Airsonic.
# This will flatten out the directory structure and also remove files in the destination that are no longer in the source.
# please test the configurable variables with rsync's --dry-run.

##  Location to search for m3u playlists recursively

# copy all m3u files to tempdir
