================
I have added the changes suggested by Emil Velikov that did not make it in the
v2.
- added .gitignore files (and removed m4/.gitkeep)
- added AC_PREREQ and LT_PREREQ
- added autogen.sh script
- fixed examples/Makefile.am (use *_LDADD instead of AM_LDFLAGS
- added -no-undefined to src/Makefile.am

Changes since v1
================
- added libgencec.pc.in file

Best wishes,
Kamil Debski

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.

+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+libGenCEC - library for the generic HDMI CEC kernel interface
+--------------------------------------------------------------------------
+
+The libGenCEC library is a simple library that was written to facilitate
+proper configuration and use of HDMI CEC devices that use the generic HDMI
+CEC kernel interface.
+
+The library provides a range of functions that wrap around the ioctls of the
+kernel API. It contains a test application that can be used to communicate
+through the CEC bus with other compatible devices.
+
+The test application also serves as a code example on how to use the library.
+
+The library calls are documented in the gencec.h file.
+
+Example application use
+--------------------------------------------------------------------------
+The following command will initiate the devic, set the name and enable
+keypress forwarding. Tested on a Samsung TV model LE32C650.
+
+./cectest -e -l playback -P -O Test123 -T -A -M on
