+# 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.
