Calling Serial.println from C++

Simple question - I'm writing a little library and I want to put in some debugging Serial.println's. How do I call that from C+?

From what I can tell, nothing special is required. I added this...

  Serial.println( "yo" );

...to a C++ library method and didn't have any problems.

Hmph, I was assuming I'd need to a add a #include - which ones have you at the top of your C++ file?

It looks like this is the only one needed…

#include <WProgram.h>

If that doesn’t work, report back and I’ll investigate further. Please include the Arduino version.

That's got it - thanks for your help.
