+# 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.

+# 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

+# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-cpu
+#

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

+# 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.
