# DEFAULTS OVERRIDE
#
# Options defined in the DEFAULTS section can not be duplicated
# even if they are defined in two different DEFAULT sections.
# This is done to catch mistakes where an option is added but
# the previous option was forgotten about and not commented.
#
# The OVERRIDE keyword can be added to a section to allow this
# section to override other DEFAULT sections values that have
# been defined previously. It will only override options that
# have been defined before its use. Options defined later
# in a non override section will still error. The same option
# can not be defined in the same section even if that section
# is marked OVERRIDE.
#
#
#
# Both TEST_START and DEFAULTS sections can also have the IF keyword
# The value after the IF must evaluate into a 0 or non 0 positive
# integer, and can use the config variables (explained below).
#
# DEFAULTS IF ${IS_X86_32}
#
# The above will process the DEFAULTS section if the config
# variable IS_X86_32 evaluates to a non zero positive integer
# otherwise if it evaluates to zero, it will act the same
# as if the SKIP keyword was used.
#
# The ELSE keyword can be used directly after a section with
# a IF statement.
#
# TEST_START IF ${RUN_NET_TESTS}
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network
#
# ELSE
#
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-normal
#
#
# The ELSE keyword can also contain an IF statement to allow multiple
# if then else sections. But all the sections must be either
# DEFAULT or TEST_START, they can not be a mixture.
#
# TEST_START IF ${RUN_NET_TESTS}
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network
#
# ELSE IF ${RUN_DISK_TESTS}
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-tests
#
# ELSE IF ${RUN_CPU_TESTS}
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-cpu

# ELSE
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network

# == and !=, strings may be used for both sides.

# DEFAULTS IF ${BOX_TYPE} == x86_32
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-32
# ELSE
# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-64

# The DEFINED keyword can be used by the IF statements too.
# It returns true if the given config variable or option has been defined
# or false otherwise.

# DEFAULTS IF DEFINED USE_CC
# CC := ${USE_CC}

#
# TEST_START IF (DEFINED ALL_TESTS || ${MYTEST} == boottest) && ${MACHINE} == gandalf
#
# Notice the use of paranthesis. Without any paranthesis the above would be
# processed the same as:
#
# TEST_START IF DEFINED ALL_TESTS || (${MYTEST} == boottest && ${MACHINE} == gandalf)
#
#
#
# INCLUDE file
#
# The INCLUDE keyword may be used in DEFAULT sections. This will
# read another config file and process that file as well. The included
# file can include other files, add new test cases or default
# statements. Config variables will be passed to these files and changes
# to config variables will be seen by top level config files. Including
# a file is processed just like the contents of the file was cut and pasted
# into the top level file, except, that include files that end with
# TEST_START sections will have that section ended at the end of
# the include file. That is, an included file is included followed
# by another DEFAULT keyword.
#
# Unlike other files referenced in this config, the file path does not need
# to be absolute. If the file does not start with '/', then the directory
# that the current config file was located in is used. If no config by the
# given name is found there, then the current directory is searched.
#
# INCLUDE myfile
# DEFAULT
#
# is the same as:
#
# INCLUDE myfile
#
# Note, if the include file does not contain a full path, the file is
# searched first by the location of the original include file, and then
# by the location that ktest.pl was executed in.
