 IMAGE may be compressed, in which case \fIbmaptool\fR decompresses it on-the-fly.
 The compression type is detected by the file extension and the following
-compression types are supported: ".bz2", ".gz", ".xz", ".gzip", ".tar.bz2",
-".tar.gz", ".tgz", ".tar.xz". If IMAGE has none of these extensions, it is
-assumed to be uncompressed.
