Since we don't have a tutorial or a how-to guide for this, I think the best way to figure out what needs to be done is to look at specific commits of a format that has recently been added. I think the best candidate is the sapH format, since it has been added recently, so that there aren't too many commits which are unrelated to tuning the format. $ git log sapH_fmt_plug.c just shows 16 commits in bleeding jumbo. Those commits related to JtR refactoring are quite easy to distinguish from commits that actually tune the format. Frank
