# DESCRIPTION OF a-kill
# ---------------------
#
# Kills all processes on target device that match a string.
#
# For example:
#
#     $ a-kill mediaserver
#
# Will kill all processes that have 'mediaserver' in the command line.
# There is usually only one called 'mediaserver'.  However:
#
#     $ a-kill media
#
# Will kill all process that have 'media' in the command line.  There
# are usually three.
#
# If you want to try first, then you can use the -d option for
# "dry run."  It will show you the processes that it would have killed.
#
# The program depends on 'adb' being in the current path, and ps being
# the default one supplied by android.  (E.g. this won't work with
# the ps supplied by busybox.)
