I downloaded http://www.lunabase.org/~faber/Vault/software/grap/grap-1.10.tar.gz and within Cygwin, after unwrapping it, I ran the commands ./configure make make install The implementation seems to have worked just fine: by this I mean (i) there were no errors reported during the make described above and (ii) everything I try running that uses grap, works. So that's good. But it isn't a Cygwin-supplied grap, so has none of the assurance that one has come to expect with the Cygwin provision. Is there some "test" I can try which would enable me to upgrade the assessment from "seems to work" to "works"?
