Help should include the other commands

[royemosby]

Is your feature request related to a problem? Please describe.

The problem is my brain where I don't remember the different commands.

Describe the solution you'd like

Include the following inside the message printed by trash --help

trash-put           trash files and directories.
trash-empty         empty the trashcan(s).
...etc

Describe alternatives you've considered

• Manual entry doesn't exist
• Going back to the github readme page.
