-
-On the other hand, symbol numbers (representing the grammar's
-non-terminals) are assigned by pgen based on the actual grammar
-input.

-Note: this module is pretty much obsolete; the pgen module generates

- do this (see the conv and pgen modules).

- file is written by calling dump() (after loading the grammar
- tables using a subclass). The report() method prints a readable
- representation of the tables to stdout, for debugging.
-
- The instance variables are as follows:
-
- symbol2number -- a dict mapping symbol names to numbers. Symbol
- numbers are always 256 or higher, to distinguish
- them from token numbers, which are between 0 and
- 255 (inclusive).
-
- number2symbol -- a dict mapping numbers to symbol names;

-
- labels -- a list of (x, y) pairs where x is either a token

- or a string; the strings are keywords. The label
- number is the index in this list; label numbers

-generate_tokens(readline) is a generator that breaks a stream of
-text into Python tokens. It accepts a readline-like method which is called
-repeatedly to get the next line of input (or "" 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
-
-Older entry points
- tokenize_loop(readline, tokeneater)
- tokenize(readline, tokeneater=printtoken)
-are the same, except instead of generating tokens, tokeneater is a callback
-function to which the 5 fields described above are passed as 5 arguments,
-each time a new token is found."""
