The lex.yy.c file was generated by Flex, but otherwise it's independent of it. It doesn't #include Flex's header files, and we don't link it to the Flex libraries. So we can do with it whatever we want.

We may find though that a stripped-down version of lex.yy.c will be rather trivial, and converting it to Python may be straightforward.

Best,
