So, there are pros and cons. We'll see!
@opindex bzip2
+@item -J
+@itemx --xz
+Filter the archive through @code{xz}. Otherwise like
+@option{--gzip}.
+
@item -j
@itemx --bzip2
Filter the archive through @code{bzip2}. Otherwise like @option{--gzip}.
@opindex lzma
@item --lzma
-@itemx -J
Filter the archive through @command{lzma}. Otherwise like @option{--gzip}.
@opindex lzop
@item --preserve
Same as both @option{--same-permissions} and @option{--same-order}.
-The @option{--preserve} option has no equivalent short option name.
-It is equivalent to @option{--same-permissions} plus @option{--same-order}.

-@FIXME{I do not see the purpose of such an option. (Neither I. FP.)
-Neither do I. --Sergey}
