Thanks for your feedback.

Maybe you could just open issues (or even better, fork the repo, make your 
changes and create pull requests). That is much easier to maintain because it 
wastes time if I have to keep in mind the contents of the discussion here 
and/or to look it all up again when I find time for coding.

I agree with changing the function name and I agree that a function to extract 
the public suffix from a given domain is useful.

Is there anybody with time to brush up the autoconf stuff (just go through it, 
fix the warnings with ./autogen.sh, fix 'make distcheck'). ?

What about API docs - would Doxygen be oversized ?
