-"""File-like objects that read/write an array buffer.
-
-This implements (nearly) all stdio methods.
-
-f = ArrayIO() # ready for writing
-f = ArrayIO(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:
-- This is very similar to StringIO. StringIO is faster for reading,
- but ArrayIO is faster for writing.
-- ArrayIO uses an array object internally, but all its interfaces
- accept and return strings.
-- 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).
