# [R-pkg-devel] Using the amsmath package in a vignette.

As I read the docs (a few months ago though), you are supposed to include
the pdf and encouraged to include sources, but the process to get pdf from
source may depend on your private libraries/data/software, and is not
replicated on CRAN checks.  This seemed to work for me as my vignette
includes a less common .bst.  I sort of remember receiving errors about
missing .bst from rhub, but it definitely ran on CRAN with no red flags
raised.
