Understanting code with greater than and less than operators

I'm trying to understand this line of code.

FastLED.addLeds<WS2812, PIN, GRB>(leds, NUM_LEDS);

It is part of ambilight.ino for Arduino and uses the FastLED library. It seems to be related to the initialization of the led stripe, but I can't understand how the < and > symbols are being used, if they are comparators or somewhat other thing...

I know a bit of coding, but this one is puzzling me.

Cheers.

I don't have many things to try, just want to understand the code.

The code is working correctly, just want to understand it.

It is a template, read more about templates here: http://www.cplusplus.com/doc/oldtutorial/templates/

You can see the definition of the template in the FastLed library here: https://github.com/FastLED/FastLED/blob/master/FastLED.h#L390
