<avr/eeprom.h> lib. included?

im using the EEPROM writeanything program and need this library so please tell me that whether this library is already there in as the arduino IDE is avr GCC compiler based or i have to get it from somewhere?

If you include it, and the compiler doesn't complain, then you know the answer, don't you?

There really are some things that you can figure out on your own.

just confirming
