Documentation request: Settings file, commandline options (maybe a --help option?)

[EvanEdwards]

I've figured out that passing a path to it uses the dirname() path as the directory to check (i.e., given /path/to/here it will launch with /path/to). That allowed me to kind of awkwardly integrate it into dolphin so I can right click on something inside the path I want to check and "Find duplicate files..." using XDG %u in the desktop file.

Are there any other commandline options? I'd like to specify a minimum size and a few other things when launching from a context menu. I also didn't see a $HOME/.config/fclones-gui or similar. Where are the settings stored? I poked around the source and even ran strings against the executable, but my rust-fu is not that of a native speaker and I didn't see it.

Adding a --help option to dump the above (any commandline arguments and options, plus the location of the settings) would probably go a long way toward improving the ease of use.

Thank you for the work done here, and apologies for no push request, you probably don't want my non-idiomatic rust code anyway.

(As an aside to others looking for information, the ~/.cache/fclones directory contains information for fclones group --cache, which is only quasi-related and quite possibly irrelevant, but I'm adding it to this issue anyway just to start coalescing documentation.)
