The people at TidBITS have released the latest in their Take Control series of books — “Take Control of BBEdit,” and it's only $5. I haven't gotten into the content yet, but I skimmed over the chapter list and it looks good. BBEdit has become an essential part of my development and writing workflows. BBEdit is my primary writing environment, what I mostly used for creating this sites theme (and the Albina Development site), how I manage project documents, write scripts and probably some other stuff I'm forgetting. If you don't have BBEdit, I recommend grabbing the demo, and then getting this book.
