  Pyperclip
  
  A cross-platform clipboard module for Python. (only handles plain text for now)
  By Al Sweigart al@inventwithpython.com
  BSD License
  
  Usage:
    import pyperclip
    pyperclip.copy('The text to be copied to the clipboard.')
    spam = pyperclip.paste()
  
    if not pyperclip.copy:
      print("Copy functionality unavailable!")
  
  On Windows, no additional modules are needed.
  On Mac, the module uses pbcopy and pbpaste, which should come with the os.
  On Linux, install xclip or xsel via package manager. For example, in Debian:
  sudo apt-get install xclip
  
  Otherwise on Linux, you will need the gtk or PyQt4 modules installed.
  
  gtk and PyQt4 modules are not available for Python 3,
  and this module does not work with PyGObject yet.
