Apologies, forgot about this, and thanks. I personally think it might have been slightly simpler to check whether `dot -Tpdf </dev/null` (or an equivalent that avoids the shell) exits successfully, instead of having to parse `dot`'s output, but since you already have it working this way, I'm also okay if you want to leave it as it is.
