#!/usr/bin/env python
# attach-android-source.py - script to attach android source to a SDK folder using symlinks
# See http://mobilepearls.com/labs/viewing-android-source-code-in-eclipse/
#
# Use as:
#       python attach-android-src.py $PATH_TO_SRC $PATH_TO_SDK_PLATFORM
# where $PATH_TO_SRC is the path to an android source checkout (the folder you run "repo init" in if
# you follow the instructions on http://source.android.com/source/download.html) and 
# $PATH_TO_SDK_PLATFORM is to a platform folder inside the android sdk folder
