What are the timestamp issues you’re referring to above?  It would be
nice if we could have our cake and eat it too.  :-)

Besides, the default in ‘cmake-build-system’ is
“-DCMAKE_BUILD_TYPE=RelWithDebugInfo” (i.e., “-O2 -g”), and I think we
should keep it this way here.

Nipick: please use two semicolons for block comments like this (one
semicolon is for margin comments).

Nitpicking here as well: it’s an /implementation/ of the protocol.
Could you also expound the description a little bit?

Since source file headers don’t say anything particular, it’s ‘gpl3+’
(“or any later version”.)

Could you send an updated patch?

OK!
