2012-10-01 Thread Brandon Falk
I would be willing to work on a SMP version of tar (initially just gzip or something). I don't have the best experience in compression, and how to multi-thread it, but I think I would be able to learn and help out. Note: I would like to make this for *BSD under the BSD license. I am aware th
