# This script is part of the ChromeOS object binary search triage process.
# It should be the first script called by the user, after the user has set up
# the two necessary build tree directories (see sysroot_wrapper/README).
#
# This script requires three arguments.  The first argument must be the name of
# the board for which this work is being done (e.g. 'daisy', 'lumpy','parrot',
# etc.).  The second argument must be the name or IP address of the chromebook
# on which the ChromeOS images will be pushed and tested. The third argument
# must be the name of the package being bisected (e.g. 'chromeos-chrome',
# 'cryptohome', etc.).
#
# This script generates common/common.sh, which generates enviroment variables
# used by the other scripts in the object file binary search triage process.
#

# Set up basic variables.
