updating the Linux kernel sources.
The path to the original Linux script must be set in the environment variable ``DPDK_CHECKPATCH_PATH``.
-This, and any other configuration variables required by the development tools, are loaded from the following

+Spell checking of commonly misspelled words

+The path to the downloaded ``dictionary.txt`` must be set

The builds can be modified via the following environmental variables:
* ``DPDK_BUILD_TEST_CONFIGS`` (target1+option1+option2 target2)
+* ``DPDK_BUILD_TEST_DIR``
* ``DPDK_DEP_CFLAGS``
* ``DPDK_DEP_LDFLAGS``
* ``DPDK_DEP_PCAP`` (y/[n])
The script internally checks for dependencies, then builds for several
combinations of compilation configuration.
+By default, each build will be put in a subfolder of the current working directory.
+However, if it is preferred to place the builds in a different location,
+the environment variable ``DPDK_BUILD_TEST_DIR`` can be set to that desired location.
+For example, setting ``DPDK_BUILD_TEST_DIR=__builds`` will put all builds
+in a single subfolder called "__builds" created in the current directory.
+Setting ``DPDK_BUILD_TEST_DIR`` to an absolute directory path e.g. ``/tmp`` is also supported.

+
+Checking ABI compatibility
+--------------------------
+
+By default, ABI compatibility checks are disabled.
+
+To enable them, a reference version must be selected via the environment
+variable ``DPDK_ABI_REF_VERSION``.
+
+The ``devtools/test-build.sh`` and ``devtools/test-meson-builds.sh`` scripts
+then build this reference version in a temporary directory and store the
+results in a subfolder of the current working directory.
+The environment variable ``DPDK_ABI_REF_DIR`` can be set so that the results go
+to a different location.
