compilation and installation
----------------------------
-make
-su
-make install
-
-should suffice on most systems. It builds libcpupower to put in
-/usr/lib; cpupower, cpufreq-bench_plot.sh to put in /usr/bin; and
-cpufreq-bench to put in /usr/sbin. If you want to set up the paths
-differently and/or want to configure the package to your specific
-needs, you need to open "Makefile" with an editor of your choice and
-edit the block marked CONFIGURATION.
+There are 2 output directories - one for the build output and another for
+the installation of the build results, that is the utility, library,
+man pages, etc...
+
+default directory
+-----------------
+
+In the case of default directory, build and install process requires no
+additional parameters:
+
+build
+-----
+
+$ make
+
+The output directory for the 'make' command is the current directory and
+its subdirs in the kernel tree:
+tools/power/cpupower
+
+install
+-------
+
+$ sudo make install
+
+'make install' command puts targets to default system dirs:
+
+-----------------------------------------------------------------------
+| Installing file | System dir |
+-----------------------------------------------------------------------
+| libcpupower | /usr/lib |
+-----------------------------------------------------------------------
+| cpupower | /usr/bin |
+-----------------------------------------------------------------------
+| cpufreq-bench_plot.sh | /usr/bin |
+-----------------------------------------------------------------------
+| man pages | /usr/man |
+-----------------------------------------------------------------------
+
+To put it in other words it makes build results available system-wide,
+enabling any user to simply start using it without any additional steps
+
+custom directory
+----------------
+
+There are 2 make's command-line variables 'O' and 'DESTDIR' that setup
+appropriate dirs:
+'O' - build directory
+'DESTDIR' - installation directory. This variable could also be setup in
+the 'CONFIGURATION' block of the "Makefile"
+
+build
+-----
+
+$ make O=<your_custom_build_catalog>
+
+Example:
+$ make O=/home/hedin/prj/cpupower/build
+
+install
+-------
+
+$ make O=<your_custom_build_catalog> DESTDIR=<your_custom_install_catalog>
+
+Example:
+$ make O=/home/hedin/prj/cpupower/build DESTDIR=/home/hedin/prj/cpupower \
+> install
+
+Notice that both variables 'O' and 'DESTDIR' have been provided. The reason
+is that the build results are saved in the custom output dir defined by 'O'
+variable. So, this dir is the source for the installation step. If only
+'DESTDIR' were provided then the 'install' target would assume that the
+build directory is the current one, build everything there and install
+from the current dir.
+
+The files will be installed to the following dirs:
+
+-----------------------------------------------------------------------
+| Installing file | System dir |
+-----------------------------------------------------------------------
+| libcpupower | ${DESTDIR}/usr/lib |
+-----------------------------------------------------------------------
+| cpupower | ${DESTDIR}/usr/bin |
+-----------------------------------------------------------------------
+| cpufreq-bench_plot.sh | ${DESTDIR}/usr/bin |
+-----------------------------------------------------------------------
+| man pages | ${DESTDIR}/usr/man |
+-----------------------------------------------------------------------
+
+If you look at the table for the default 'make' output dirs you will
+notice that the only difference with the non-default case is the
+${DESTDIR} prefix. So, the structure of the output dirs remains the same
+regardles of the root output directory.
+
+
+clean and uninstall
+-------------------
+
+'clean' target is intended for cleanup the build catalog from build results
+'uninstall' target is intended for removing installed files from the
+installation directory
+
+default directory
+-----------------
+
+This case is a straightforward one:
+$ make clean
+$ make uninstall
+
+custom directory
+----------------
+
+Use 'O' command line variable to remove previously built files from the
+build dir:
+$ make O=<your_custom_build_catalog> clean
+
+Example:
+$ make O=/home/hedin/prj/cpupower/build clean
+
+Use 'DESTDIR' command line variable to uninstall previously installed files
+from the given dir:
+$ make DESTDIR=<your_custom_install_catalog>
+
+Example:
+make DESTDIR=/home/hedin/prj/cpupower uninstall
+
+
+running the tool
+----------------
+
+default directory
+-----------------
+
+$ sudo cpupower
+
+custom directory
+----------------
+
+When it comes to run the utility from the custom build catalog things
+become a little bit complicated as 'just run' approach doesn't work.
+Assuming that the current dir is '<your_custom_install_catalog>/usr',
+issuing the following command:
+
+$ sudo ./bin/cpupower
+will produce the following error output:
+./bin/cpupower: error while loading shared libraries: libcpupower.so.1:
+cannot open shared object file: No such file or directory
+
+The issue is that binary cannot find the 'libcpupower' library. So, we
+shall point to the lib dir:
+sudo LD_LIBRARY_PATH=lib64/ ./bin/cpupower

+This folder contains the necessary files to build the Python bindings for
+libcpupower (aside from the libcpupower object files).
+
+
+requirements
+------------
+
+* You need the object files in the libcpupower directory compiled by
+cpupower's makefile.
+* The SWIG program must be installed.
+* The Python's development libraries installed.
+
+Please check that your version of SWIG is compatible with the version of Python
+installed on your machine by checking the SWIG changelog on their website.
+https://swig.org/
+
+Note that while SWIG itself is GPL v3+ licensed; the resulting output,
+the bindings code: is permissively licensed + the license of libcpupower's .o
+files. For these bindings that means GPL v2.
+
+Please see https://swig.org/legal.html and the discussion [1] for more details.
+
+[1]
+https://lore.kernel.org/linux-pm/Zqv9BOjxLAgyNP5B@hatbackup/
+
+
+build
+-----
+
+Install SWIG and the Python development files provided by your distribution.
+
+Build the object files for libcpupower by running make in the cpupower
+directory.
+
+Return to the directory this README is in to run:
+
+$ make
+
+
+testing
+-------
+
+Please verify the _raw_pylibcpupower.so and raw_pylibcpupower.py files have
+been created.
+
+To run the test script:
+
+$ python test_raw_pylibcpupower.py
