Handle Cygwin Path in Sublime

cygpath.py

import os
import re
import sublime

cygwin_drive_regex = re.compile(r"^/cygdrive/([a-zA-Z])/")

def cygwin_path_handle(path):
    """Cygwin Path Support"""
    if sublime.platform() == "windows":
        return os.path.normcase(re.sub(cygwin_drive_regex, lambda m: "%s:/" % m.groups()[0], path))
    else:
        return path  # do nothing if it is not under windows.

Could you tell me how to use this. I suppose this is exactly what I'm searching for, but I don't know how to use this code in sublime.
