    "Commit 8235c68f11b4fad5e24849a01d04ea153c29ee28. The README calls openrsync an implementation of rsync with a BSD (ISC) license, compatible with rsync 3.1.3 and with any peer that supports protocol 27. rsync.5 says it is compatible with version 27 of the reference. The officially supported system is OpenBSD.",
    "regress/functional/conf.sh sets rsync to ./openrsync unless that variable is already set. test00_simple.test creates dir1/one.txt with mkdirfile, builds the same file under dir2/dir1, runs $rsync -a dir1 dir3, and calls compare_trees dir2 dir3. compare_trees diffs file listings, directory listings, and then file contents with diff -ru. make regress_functional runs these tests.",
