+"""Module to analyze Python source code; for syntax coloring tools.
+
+Interface:
+ tags = fontify(pytext, searchfrom, searchto)
+
+The 'pytext' argument is a string containing Python source code.
+The (optional) arguments 'searchfrom' and 'searchto' may contain a slice in pytext.
+The returned value is a list of tuples, formatted like this:
+ [('keyword', 0, 6, None), ('keyword', 11, 17, None), ('comment', 23, 53, None), etc. ]
+The tuple contents are always like this:
+ (tag, startindex, endindex, sublist)
+tag is one of 'keyword', 'string', 'comment' or 'identifier'
+sublist is not used, hence always None.
