Since I typeset a lot of math with delimiters, these appear to be incredibly useful. Unfortunately, after looking in Guide to LaTeX, The LaTeX Companion, More Math Into LaTeX, and doing a bit of DuckDuckGoing, I have not been able to find anything that documents these commands (just a few examples of their use). Can anyone out there point me to a site that documents these two commands?

I have The TeXBook and did not look there. I just had a look and it looks like I will be able to decipher what I need. Thank you!
