# Pyperclip v1.3
# A cross-platform clipboard module for Python. (only handles plain text for now)
# By Al Sweigart al@coffeeghost.net

# Usage:
#   import pyperclip
#   pyperclip.copy('The text to be copied to the clipboard.')
#   spam = pyperclip.paste()

# On Mac, this module makes use of the pbcopy and pbpaste commands, which should come with the os.
# On Linux, this module makes use of the xclip command, which should come with the os. Otherwise run "sudo apt-get install xclip"

# Change Log:
# 1.2 Use the platform module to help determine OS.
# 1.3 Changed ctypes.windll.user32.OpenClipboard(None) to ctypes.windll.user32.OpenClipboard(0), after some people ran into some TypeError
