+"os - OS routines for NT or Posix depending on what system we're on.
+
+This exports:
+      - all functions from posix or nt, e.g. unlink, stat, etc.
+      - os.path is either posixpath or ntpath
+      - os.name is either 'posix' or 'nt'
+      - os.curdir is a string representing the current directory (always '.')
+      - os.pardir is a string representing the parent directory (always '..')
+      - os.sep is the (or a most common) pathname separator ('/' or '\\')
+      - os.extsep is the extension separator (always '.')
+      - os.altsep is the alternate pathname separator (None or '/')
+      - os.pathsep is the component separator used in $PATH etc
+      - os.linesep is the line separator in text files ('\r' or '\n' or '\r\n')
+      - os.defpath is the default search path for executables
+      - os.devnull is the file path of the null device ('/dev/null', etc.)
+
+    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
+    (e.g., split and join).
