It takes a single +argument (a `keyword'), identifying the class of warning messages +to affect. If the argument is prefixed with `no-', such warning +messages are suppressed. For example, + + tar --warning=no-alone-zero-block -x -f archive + +suppresses the output of `A lone zero block' diagnostics, which is +normally issued if `archive' ends with a single block of zeros. + +See Tar Manual, section 3.9 "Controlling Warning Messages", for a +detailed discussion. + +* New command line option `--level' + +The `--level=N' option sets the incremental dump level N.
