Concentrating on a spell

[Theroc]

When concentrating to maintain a spell, what actions can, and cannot be taken by the player maintaining the spell? Does it take only the players standard action each round? Or is it a full-round action every round?

Concentration

The spell lasts as long as you concentrate on it. Concentrating to maintain a spell is a standard action that does not provoke attacks of opportunity. Anything that could break your concentration when casting a spell can also break your concentration while you’re maintaining one, causing the spell to end.
You can’t cast a spell while concentrating on another one. Sometimes a spell lasts for a short time after you cease concentrating.

Where was that? I couldn't find it in the SRD's magic overview.

It's in the section on reading the spells, specifically duration. Here
