# pmp3p - "Populate" MP3 Player
#
# Copyright © 2009, 2010 by Daniel Friesel <derf@derf.homelinux.org>
# License: WTFPL <http://sam.zoy.org/wtfpl>
#
# Usage: pmp3p [--remove] <basedir> <files ...>
#
# Requires: atag/arename, oggdec, flac, lame
# For playlist generation: sed, unix2dos
#
# pmp3p will put all files into basedir, more specifically to
# basedir/artist/album/id_title.mp3 .
#
# If the --remove option is specified, pmp3p will try to remove files which
# are present in basedir but not mentioned on the commandline
#
# I use it like this:
# I put symlinks to everything I want on my music player into
# ~/lib/audio/.mp3-player, then regularly call
# cd ~/lib/audio/.mp3-player
# pmp3p --remove /data/derf/sansa-tmp/MUSIC ***/*(-.)
#
# /data/derf/sansa-tmp is then later (whenever the player is connected for
# recharing) synced onto it.
# Of course, you can also directly encode to your music player.
#
# Playlist support:
# This is very specific to the "Sansa Fuze", for other players it's probably
# useless.
# Put glob expressions (one per line) to the songs you want in the playlist
# into .playlists/playlist_name .
# pmp3p will then expand those expressions and put the correct filenames into
# the playlist.
# Example:
# remnant ~/l/a/.mp3-player > cat .playlists/chill
# bluechel/*/*
# schiller/*
#
# PS: Yes, I know that the Sansa Fuze also supports flac and ogg.
# And of course: No warranty for lost data or whatever else might happen.
