A way to show binded environment variables in the help text

joy4eg opened this issue · comments

Hey there!

It would be nice if we will have an option/flag to show binded Envar's in the help text (probably for --help-long or --help-man).
Something like this:

-i, --interval=0      set commit interval (From ENV MY_APP_COMMIT_INTERVAL)

Thoughts ?
