Now:

Usage: ./mixxx [options] file
Mixxx is an open source DJ software. For more information, see: https://manual.mixxx.org/2.4/chapters/appendix/commandline_dev_tools.html

Options:
  -f, --full-screen          Starts Mixxx in full-screen mode
  --locale                   Use a custom locale for loading translations. (e.g
                             'fr')
  --settings-path <path>     Top-level directory where Mixxx should look for
                             settings. Default is:/home/sperry/.mixxx/
  --resource-path <path>     Top-level directory where Mixxx should look for
                             its resource files such as MIDI mappings,
                             overriding the default installation location.
  --timeline-path <path>     Path the debug statistics time line is written to
  --controller-debug         Causes Mixxx to display/log all of the controller
                             data it receives and script functions it loads
  --developer                Enables developer-mode. Includes extra log info,
                             stats on performance, and a Developer tools menu.
  --safe-mode                Enables safe-mode. Disables OpenGL waveforms, and
                             spinning vinyl widgets. Try this option if Mixxx is
                             crashing on startup.
  --color <color>            [auto|always|never] Use colors on the console
                             output.
  --log-level <level>        Sets the verbosity of command line logging.
                             critical - Critical/Fatal only
                             warning  - Above + Warnings
                             info     - Above + Informational messages
                             debug    - Above + Debug/Developer messages
                             trace    - Above + Profiling messages
  --log-flush-level <level>  Sets the the logging level at which the log buffer
                             is flushed to mixxx.log. <level> is one of the
                             values defined at --log-level above.
  --debug-assert-break       Breaks (SIGINT) Mixxx, if a DEBUG_ASSERT evaluates
                             to false. Under a debugger you can continue
                             afterwards.
  -h, --help                 Displays this help.
  -v, --version              Displays version information.

Arguments:
  file                       Load the specified music file(s) at start-up. Each
                             file you specify will be loaded into the next
                             virtual deck.

This line is really long:

Mixxx is an open source DJ software. For more information, see: https://manual.mixxx.org/2.4/chapters/appendix/commandline_dev_tools.html

How about putting the URL on its own line?

@Be-ing: merge?

Already approved, I'll hit merge.

This PR breaks the legacy command line arguments. I was wondering why Mixxx no longer finds my settings path when using --settingsPath although it still exists. Mixxx stops with an assertion on startup and complains that it is not able to open the database.
