I have finally gotten around to integrating Fritz’s patch in to my version of ObHack, which I call “ObHack-006b-pl1” (ObHack release 006b patchlevel 1). This is simply ObHack 006b with Fritz’s patch.
Barring a security hole in ObHack, this will be my last ObHack release. Fritz is the current maintainer and has made a lot of improvements and changes which I encourage people to download and use. Also, Andrew has very recently made a release of Oblige which makes some impressive maps.
