+4.41. Q. How do I delete a file?  And other file questions.
+
+A. Use os.remove(filename) or os.unlink(filename); for documentation,
+see the posix section of the library manual.  They are the same,
+unlink() is simply the Unix name for this function.  In earlier
+versions of Python, only os.unlink() was available.
+
+To remove a directory, use os.rmdir(); use os.mkdir() to create one.
+
+To rename a file, use os.rename().
+
+To truncate a file, open it using f = open(filename, "w+"), and use
+f.truncate(offset); offset defaults to the current seek position.
+There's also os.ftruncate(fd, offset) for files opened with os.open()
+-- for advanced Unix hacks only.
