The --max-count test was simple to put together.

Of course its in Git. :-) There's no webpage here, but you can clone it: http://www.spearce.org/projects/scm/egit.git The code you would recognize most is in org.spearce.jgit/.../lib. E.g. BinaryDelta.java came from patch-delta.c in core Git. Repository has some of the functionality of sha1_file.c, the pack reading code is in PackFile.java. -- Shawn. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
