[OS X TeX] Strategy for saving TikZ or PGF output as separate files?

[Michael Kubovy]

Dear Friends,

I have been using TikZ and pgf for a while now, and am very  
satisfied. I am about to publish my first paper with figures produced  
with these tools and I need to submit the figures separately  
(eventually as TIFF, I believe). Regardless of format is there a  
straightforward strategy for producing the figures as separate files,  
without creating a new .tex file for each figure?
