+Class and program to colorize python source code for ANSI terminals.
+
+Based on an HTML code highlighter by Jurgen Hermann found at:

+
+Modifications by Fernando Perez (fperez@colorado.edu).

+
+Title: Colorize Python source using the built-in tokenizer
+
+Submitter: Jurgen Hermann
+Last Updated:2001/04/06
+
+Version no:1.2
+
+Description:
+
+This code is part of MoinMoin (http://moin.sourceforge.net/) and converts
+Python source code to HTML markup, rendering comments, keywords,
+operators, numeric and string literals in different colors.
+
+It shows how to use the built-in keyword, token and tokenize modules to
+scan Python source code and re-emit it with no changes to its original
+formatting (which is the hard part).
