# Shamelessly stolen from:

# An example hook script to verify what is about to be committed.
# Called by "git commit" with no arguments.  The hook should
# exit with non-zero status after issuing an appropriate message if
# it wants to stop the commit.
#
# To enable this hook, rename this file to "pre-commit".

Folgendes Problem zu libmunin:

• Ich hab eine Liste von Songs.
• Um Aussagen über deren ähnlichkeit zu machen muss ich die untereinander vergleichen. Das ergibt für N Songs ((N - 1) ^ 2 / 2) Vergleiche. Für N=32k ne ganze Menge. (Abgeschätzte Zeit wären ca. 13h, also unakzeptabel.)

Es seien zwei variabel lange Listen mit variabel langen Tupeln darin:

a = [(85, 0), (190, 2), (190, 6)]
b = [(85, 0), (190, 2, 0), (190, 2, 0), (190, 6)]

Die Listen sind stets sortiert, kleinste Werte zuerst. Es soll eine Distanzfunktion geschrieben werden die diese beiden Listen auf Ähnlichkeit untersucht. Diese Funktion soll eine Zahl zwischen 0.0 (volle ähnlichkeit) und 1.0 (volle divergenz) ergeben.

/*
 * Compile: gcc mpdsonglisten.c -o mpdsonglisten -lmpdclient -std=c99 
 * Run: ./mpdsonglisten localhost 6600 <on_play_script> <on_stop_script>
* Example: ./mpdsong localhost 6600 'echo plays!' 'echo stopped!'
* 
* It will call on_play_script once mpd starts playing,
* and on_stop_script once it pauses, stops or does something unknown.
*
* Error handling is done by ignoring none-fatal erros and trying to reconnect if
* fatal errors happen.
