syntax highlighted code

[Neal Becker]

I want to put hyperlinks in my pdf output to syntax highlighted code
listings.  I wonder if anyone can recommend a syntax highlighter that:

1) groks c++ and python (at least)
2) outputs pdf
3) Can number lines
4) Can wrap long lines

I don't want to include the code listings in my main document (because they
are long), I just want hyperlinks to them.
