The post_by_Max_Bruning.md is a re-formatted copy of a post written by Mr. Max Bruning, that was probably written around 2013-03-26.
This is just a re-formatted, easier-to-read version of that great but awfully formatted post.
I do can compile the attached main.cpp
(I had to slightly modify it), and the resulting raidzdump
executable produces the same result as in the original post, namely
>> raidzdump ./raidzdump 14c00 20000 5
