-You can use @option{--gzip} and @option{--gunzip} on physical devices
-(tape drives, etc.) and remote files as well as on normal files; data
-to or from such devices or remote files is reblocked by another copy
-of the @command{tar} program to enforce the specified (or default) record
-size. The default compression parameters are used; if you need to
-override them, set @env{GZIP} environment variable, e.g.:
+@opindex xz
+@item -J
+@itemx --xz
+Filter the archive through @code{xz}.
+
+@item -j
+@itemx --bzip2
+Filter the archive through @code{bzip2}.
+
+@opindex lzip
+@item --lzip
+Filter the archive through @command{lzip}.
+
+@opindex lzma
+@item --lzma
+Filter the archive through @command{lzma}.
+
+@opindex lzop
+@item --lzop
+Filter the archive through @command{lzop}.
+
+@opindex compress
+@opindex uncompress
+@item -Z
+@itemx --compress
+@itemx --uncompress
+Filter the archive through @command{compress}.
+@end table
+
+When any of these options is given, @GNUTAR{} searches the compressor
+binary in the current path and invokes it. The name of the compressor
+program is specified at compilation time using a corresponding
+@option{--with-@var{compname}} option to @command{configure}, e.g.
+@option{--with-bzip2} to select a specific @command{bzip2} binary.
+@xref{lbzip2}, for a detailed discussion.
+
+The output produced by @command{tar --help} shows the actual
+compressor names along with each of these options.

+You can use any of these options on physical devices (tape drives,

+@command{tar} program to enforce the specified (or default) record

+programs allow to override these by setting a program-specific
+environment variable. For example, when using @command{gzip} you can
+use @env{GZIP} as in the example below:
