Optional `-C` and `--dir` options are added to the `-x` main operation of the jar tool. The value for these options is expected to be a file path which is expected to be a directory to which the jar will be extracted. When neither `-C` nor `--dir` are used, the extract operation of the jar tool will continue to behave like it did before this enhancement and will extract the jar into the current working directory.

This text _valid in any mode_ was present in earlier releases but does not seem to have been true for `-C` with `-x`.
