+Usage:
+ $program init gpg-id
+ Initialize new password storage and use gpg-id for encryption.
+ $program [ls] [subfolder]
+ List passwords.
+ $program [show] [--clip,-c] pass-name
+ Show existing password and optionally put it on the clipboard.
+ If put on the clipboard, it will be cleared in 45 seconds.
+ $program insert [--multiline,-m] pass-name
+ Insert new optionally multiline password.
+ $program generate [--no-symbols,-n] [--clip,-c] pass-name pass-length
+ Generate a new password of pass-length with optionally no symbols.
+ Optionally put it on the clipboard and clear board after 45 seconds.
+ $program rm pass-name
+ Remove existing password.
+ $program push
+ If the password store is a git repository, push the latest changes.
+ $program pull
+ If the password store is a git repository, pull the latest changes.
+ $program git git-command-args...
+ If the password store is a git repository, execute a git command
+ specified by git-command-args.
+ $program help
+ Show this text.
