      3 # type passwords with xdotool, messages with zenity
      4 # usage: choose a FILE in the dmenu to type the password for it
      5 # type "FILE USER" to generate a new password for FILE and type it
      6 # (additionally storing "USER" as second line in the file)
      7 
      8 # for this script to work, you need a pinentry wrapper that prompts using GTK,
      9 # see e.g., my-pinentry which prompts in curses or GTK depending on environment
     10 
     11 # inspired by similar scripts, e.g.:
     12 # https://gist.github.com/ivyl/7429582
     13 # http://www.christoph-egger.org/weblog/entry/48
     14 # http://git.zx2c4.com/password-store/tree/contrib/dmenu/passmenu (ships with pass)
     15 # https://github.com/carnager/rofi-pass (much more featureful)
