18 -d, --debug
19 makes mu generate extra debug information, useful for debugging the
20 program itself. By default, debug information goes to the log file,
21 ~/.cache/mu/mu.log. It can safely be deleted when mu is not running.
22 When running with --debug option, the log file can grow rather quickly.
23 See the note on logging below.

25
26 -q, --quiet
27 causes mu not to output informational messages and progress information
28 to standard output, but only to the log file. Error messages will still

30 --quiet, so it is recommended you use this option when using mu from
31 scripts etc.
