# Script to perform the build of Android on another machine
# By performing such a build of severely time on another machine, 
# it is possible to ensure the CPU resources of the development machine, 
# it is possible to prevent the "can not do anything during the build" state
#
# Install
# 1. this file create to project root dir.
# 2. please setting. env.hosts, module, flavor, debug.
# 3. run this
# $ fab build

# fabric install
# sudo env ARCHFLAGS="-arch i386 -arch x86_64" pip install fabric
