#
#### Config variables ####
#
# This config file can also contain "config variables".
# These are assigned with ":=" instead of the ktest option
# assigment "=".
#
# The difference between ktest options and config variables
# is that config variables can be used multiple times,
# where each instance will override the previous instance.
# And that they only live at time of processing this config.
#
# The advantage to config variables are that they can be used
# by any option or any other config variables to define thing
# that you may use over and over again in the options.
#
# For example:
#
# USER := root
# TARGET := mybox
# TEST_CASE := ssh ${USER}@${TARGET} /path/to/my/test
#
# TEST_START
# MIN_CONFIG = config1
# TEST = ${TEST_CASE}
#
# TEST_START
# MIN_CONFIG = config2
# TEST = ${TEST_CASE}
#
# TEST_CASE := ssh ${USER}@${TARGET} /path/to/my/test2
#
# TEST_START
# MIN_CONFIG = config1
# TEST = ${TEST_CASE}
#
# TEST_START
# MIN_CONFIG = config2
# TEST = ${TEST_CASE}
#
# TEST_DIR := /home/me/test
#
# BUILD_DIR = ${TEST_DIR}/linux.git
# OUTPUT_DIR = ${TEST_DIR}/test
#
# Note, the config variables are evaluated immediately, thus
# updating TARGET after TEST_CASE has been assigned does nothing
# to TEST_CASE.
#
# As shown in the example, to evaluate a config variable, you
# use the ${X} convention. Simple $X will not work.
#
# If the config variable does not exist, the ${X} will not
# be evaluated. Thus:
#
# MAKE_CMD = PATH=/mypath:${PATH} make
#
# If PATH is not a config variable, then the ${PATH} in
# the MAKE_CMD option will be evaluated by the shell when
# the MAKE_CMD option is passed into shell processing.
#### Using options in other options ####
#
# Options that are defined in the config file may also be used
# by other options. All options are evaulated at time of
# use (except that config variables are evaluated at config
# processing time).
#
# If an ktest option is used within another option, instead of
# typing it again in that option you can simply use the option
# just like you can config variables.
#
# MACHINE = mybox
#
# TEST = ssh root@${MACHINE} /path/to/test
#
# The option will be used per test case. Thus:
#
# TEST_TYPE = test
# TEST = ssh root@{MACHINE}
#
# TEST_START
# MACHINE = box1
#
# TEST_START
# MACHINE = box2
#
# For both test cases, MACHINE will be evaluated at the time
# of the test case. The first test will run ssh root@box1
# and the second will run ssh root@box2.
