I saw someone using the [final] option for the beamer documentclass and wanted to see what it did. So I searched the package documentation here on CTAN and also found the directory on my computer that has the beamer source (/usr/local/texlive/2015/texmf-dist/tex/latex/beamer on my machine) and then searched the files recursively for the word "final" (using grep -R final ./*) with no interesting results.
So my question is: where can one find the meaning of arbitrary documentclass options?
I am really surprised that looking through the source itself didn't yield the answer, since at some point, the options have to be parsed, I assume...
[final]
option – only a[draft]
option. Perhaps it is an option for a package that beamer loads without option? Normally the options are described in the documentation (texdoc beamer
).
