--help does not list commands

[Christoffer Anselm]

Issuing s4cmd --help yields Usage: s4cmd [options] and lists a lot of options, but implies that there are only options, no commands:

$ s4cmd --help
Usage: s4cmd [options]

Super S3 command line tool. Version 2.1.0

Options:
...

Still unsurprisingly just running s4cmd with all optional options omitted will yield [Invalid Argument] No command provided so the documentation printed with --help is wrong on that regard:

$ s4cmd
[Invalid Argument] No command provided

This is inconsistent and forces the user to look up the commands on the internet since the man page just reproduces the incomplete/wrong information of the --help option.

In my opinion the --help option and the man page should list all command listed in the README.md, so this tool becomes usable without having to look up the source repository first.
