-# class StringIO implements  file-like objects that read/write a
-# string buffer (a.k.a. "memory files").
-#
-# This implements (nearly) all stdio methods.
-#
-# f = StringIO()      # ready for writing
-# f = StringIO(buf)   # ready for reading
-# f.close()           # explicitly release resources held
-# flag = f.isatty()   # always false
-# pos = f.tell()      # get current position
-# f.seek(pos)         # set current position
-# f.seek(pos, mode)   # mode 0: absolute; 1: relative; 2: relative to EOF
-# buf = f.read()      # read until EOF
-# buf = f.read(n)     # read up to n bytes
-# buf = f.readline()  # read until end of line ('\n') or EOF
-# list = f.readlines()# list of f.readline() results until EOF
-# f.write(buf)        # write at current position
-# f.writelines(list)  # for line in list: f.write(line)
-# f.getvalue()        # return whole file's contents as a string
-#
-# Notes:
-# - Using a real file is often faster (but less convenient).
-# - fileno() is left unimplemented so that code which uses it triggers
-#   an exception early.
-# - Seeking far beyond EOF and then writing will insert real null
-#   bytes that occupy space in the buffer.
-# - There's a simple test set (see end of this file).
