# callergroup - Assign Ringtone By Caller-Group for N900 v0.0.1
# By 9000 @ maemo.org 14-May-2010
# 
# ATTENTION: Use the script at your own risk. You're responsible for any damage that'd cause by using this script.
#
# LIMITATION: Lots. Like lacking fancy UI,  insufficient format support (WAV only), etc. 
#
# FEATURE: 1) Assign different ringtones to caller-groups you defined. 
#
# Usage: 
# (Move your default ringtone to /home/user/.local/share/sounds/callergroup/ , I choose Gradient.acc.wav in this example)
# mkdir -p /home/user/.local/share/sounds/callergroup/
# mv /home/user/.local/share/sounds/Gradient.acc.wav /home/user/.local/share/sounds/callergroup/.
#
# (Symlink your default ringtone back to /home/user/.local/share/sounds/ , Gradient.aac.wav in this example)
# ln -sf /home/user/.local/share/sounds/callergroup/Gradient.aac.wav /home/user/.local/share/sounds/Gradient.aac.wav
#
# (Copy any wav files you'd like to set for the groups. I use ringtone_for_group_X.wav in this example)
# cp /media/mmc1/ringtone/*.wav /home/user/.local/share/sounds/callergroup/. (just an example)
#
# (Run the script)
# /usr/bin/python ./callergroup.py
#
