# callergroup - Assign Ringtone By Caller-Group for N900 v0.0.2
# By 9000 @ maemo.org/phonehk.com 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. 2) Block calls
# CHANGELOG: 18-May-2010: Add blocking function
#
# Usage: 
# 1) 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/.
#
# 2) 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
#
# 3) 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)
#
# 4) Customize the telephone number and ringtone file name in the CUSTOMIZATION section below
#
# 5) Run the script
# /usr/bin/python ./callergroup.py
#
