Sun Salutations

I have realized that one of the (many!) weaknesses in my yoga practice is my lack of incorporating Sun Salutations. Surprisingly, there's a lot of discussion about Sun Salutations and how they do/do not fit into an Iyengar-style Yoga practice, but not many comprehensible descriptions of what comprises said Sun Salutation. I found a couple of videos, but still, they were meant to be demonstrations of a principle or style rather than a guide on which poses to sequence.

So I shall continue seeking, perhaps look for printed reference material instead, and perhaps write about it here when I find a decent answer.
