[`icon::IconTheme`]

--headings
Show block headings
--json Output as json format after sorting, filters and tree settings are applied; without -tree will be
flattened dump of devices
--from-json=FROM_JSON
Read from json output rather than profiling system
-F, --force-libusb
Force pure libusb profiler on macOS rather than combining system_profiler output
Has no effect on other platforms or when using nusb
-c, --config=CONFIG
Path to user config file to use for custom icons, colours and default settings
-z, --debug
Turn debugging information on. Alternatively can use RUST_LOG env: INFO, DEBUG, TRACE

Use the system_profiler command on macOS to get USB data
If not using nusb this is the default for macOS, merging with libusb data for verbose output. nusb
uses IOKit directly so does not use system_profiler by default

Print version
