question about libraries

Hello there,
I cannot find answer to my next question: How to import io library to Arduino. For example, if I write
#include < avr/io.h >
and I get this result when verifying:
22: error: avr/io.h : No such file or directory In function 'void setup()':

I saw sth. that I should import libraries into arduino-0007/lib/targets/libraries/. But where to find all of those libraries (especially in that kind of structure as files in that map look like)?

Thanks for help,
Vito.

It should just happen. The way you typed it in the forum, you have spaces inside the angle brackets. It should not have spaces. You want it to be like this...

#include <avr/io.h>

Thanks, that was really an issue!
Vito.
