Hi,

Indeed you should. There will need to be some related changes there, but
off the top of my head, I don't think much more than cosmetics has changed
since the additional of flat-bottomed position restraints, so
https://github.com/gromacs/gromacs/commit/3444f61970de5c9aa5894855c8c4732b850b6737
is probably quite a good model for you.
