When I run pdflatex on the same .tex file twice, it produces similar results to my eyes but the contents of the file are slightly different (as revealed with an md5 checksum). Is there any flag I can pass to pdflatex that will keep the output consistent?
What environment sensitive metadata might be in my pdf? How can I control it?
Update: Doing a diff -a, I find the following:
