+ (description
+ "lbzip2 is a multi-threaded compression utility with support for the
+bzip2 compressed file format. lbzip2 can process standard bz2 files in
+parallel. It uses POSIX threading model (pthreads), which allows it to take
+full advantage of symmetric multiprocessing (SMP) systems. It has been proven
+to scale linearly, even to over one hundred processor cores. lbzip2 is fully
+compatible with bzip2 – both at file format and command line level.")
