# DESCRIPTION OF a-push-installed
# -------------------------------
#
# After rebuilding something marginally for android
# (e.g. libtinyalsa.so), if you capture the output of 'make' then you
# can use this script to push to the device /only/ the new files.
#
# Before executing this command, you /must/ be root on the device and
# have /system remounted read/write:
#
#     $ adb root
#     $ adb remount
#
# Typical usage (from inside your 'mydroid' folder):
#
#     $ m libfoo 2>&1 | tee log.txt
#     $ a-push-installed log.txt .
#
# This is especially helpful when you're inside a module:
#
#     $ cd external/foo
#     $ mm 2>&1 | tee log.txt
#     $ a-push-installed log.txt ../..
#
# The program depends on 'adb' being in the current path.
#
