-"""Tokenization help for Python programs.
-
-tokenize(readline) is a generator that breaks a stream of bytes into
-Python tokens.  It decodes the bytes according to PEP-0263 for
-determining source file encoding.
-
-It accepts a readline-like method which is called repeatedly to get the
-next line of input (or b"" for EOF).  It generates 5-tuples with these
-members:
-
-    the token type (see token.py)
-    the token (a string)
-    the starting (row, column) indices of the token (a 2-tuple of ints)
-    the ending (row, column) indices of the token (a 2-tuple of ints)
-    the original line (string)
-
-It is designed to match the working of the Python tokenizer exactly, except
-that it produces COMMENT tokens for comments and gives type OP for all
-operators.  Additionally, all token lists start with an ENCODING token
-which tells you which encoding was used to decode the bytes stream.
