Xar (short for eXtensible ARchive format) is an open source file archiver and the archiver’s file format. It was created within the OpenDarwin project and is used in Mac OS X 10.5 for software installation routines, as well as browser extensions in Safari 5.0. Xar replaced the use of gzipped pax files.[1]
One development branch of RPM, RPM5, uses xar.[2]
