By the way, I use xz as opposed to 7z simply because it has a simpler command line, and supports piping from stdin to stdout at the same time (http://stackoverflow.com/questions/1287383/not-able-to-use-7-zip-to-compress-stdin-and-output-with-stdout). _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
