Source Code
In this page you can download the source code, you can modify and to adapt to Wireshark version.
It is realesed as GPL's license.
Periodically it is a mandatory task, as a general rule there is need to align the plugin with the Wireshark's version. If there are improvements or modifications in the general code, the plugin could not be run.
I suggest to follow the tutorial realesed with Wireshark.
There are hints relative to every OSes, but sometimes you need a bit of patience to adapt, in any case no news for everyone that develops code.
I will continue to upgrade periodically it, a good news for lazy people :)
