+# - os.path is either module path or macpath
+# - os.name is either 'posix' or 'mac'
+# - os.curdir is a string representing the current directory ('.' or ':')

+# Programs that import and use 'os' stand a better chance of being
+# portable between different platforms.  Of course, they must then
+# only use functions that are defined by all platforms (e.g., unlink
+# and opendir), and leave all pathname manipulation to os.path
