A fully rigorous checker would indeed be too complicated, but all we really need is a program armed with sufficient heuristics to catch all the problems with existing gfn files, and it turns out that wasn't too hard to write. There's source code and binaries for Windows and Mac at https://sourceforge.net/projects/gretl/files/misc/ where you can also find a README that describes the program. In my testing, this catches all the issues with current packages, with no false positives or false negatives. I'm therefore in a position to auto-correct the packages that are affected, but I don't want to tread on anyone's toes. If you're the author of a package noted at http://lists.wfu.edu/pipermail/gretl-devel/2017-February/007411.html and you haven't already fixed your package(s), and you want to do that yourself (that is, you do _not_ want to have auto-correction applied), please let me know. Just to be clear: auto-correction would involve: * replacing "=" with "==" wherever the latter is correct; * incrementing the package version by the minimal increment; * setting the package date to the current date; and * nothing else.
