Password Store
by Jason Donenfeld
   Jason@zx2c4.com

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 [--no-echo,-n | --multiline,-m] pass-name
        Insert new password. Optionally, the console can be enabled to not
        echo the password back. Or, optionally, it may be multiline.
    $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.
