Replace previous Shell draft-quality implementation of uvol with a rewrite in ucode[1]. While the new code is slightly larger, it performs much better (as we no longer fork() for parsing strings like in Shell with grep, sed and friends). Before: time uvol list -j [ ... ] real 0m 0.82s user 0m 0.13s sys 0m 0.10s After: time uvol list -j [ ... ] real 0m 0.47s user 0m 0.05s sys 0m 0.05s [1]: https://github.com/jow-/ucode Signed-off-by: Daniel Golle <daniel@makrotopia.org>
