+Use of bzip2, which is intended to replace bzip, is recommended.
+The algorithms used in bzip2 are different and incompatible with
+those used in bzip.  To open .bz archives, you must use bzip, and
+to open .bz2 archives you must use bzip2.  Although bzip2 sometimes
+yields slightly larger output, it is faster, more reliable, maintained,
+much more widely used and is believed to be patent-free.
