Hi, My reference installation of context is from 2016-09-18. Suddenly it has stopped working. When I try to rebuild the formats (--make) it cant find context.lua. I have traced system calls, and it does not look in the right directories. If I copy mtx-context.lua to ./context.lua then it works. Other installations do work. According to Murphys Law, it is only the really important one that has stopped working. It must be something that I have done. But what? I have compared directory trees from about the seame time, but not found anything that motivates this failure. The best thing would be to have the original tree from that date, but I don't have a copy. All of the above is just background. Here comes the question: Is there a way that I can install context as it would have been installed on a given date? I mean all of context, not just the binaries. /Lars
