#' Journal of Open Source Software (JOSS) format.
#'
#' Format for creating a Journal of Open Source Software (JOSS) or Journal of
#' Open Source Education (JOSE) articles. Adapted
#' from <https://github.com/openjournals/whedon>. As these journals take
#' articles as markdown, this format can be used to generate markdown from
#' R Markdown and to locally preview how the article will appear as PDF.
#'
#' The following variables may be set in YAML metadata to populate fields in the
#' article PDF, but are only necessary fo local preview:
#' `formatted_doi, citation_author, year, volume, issue, page, submitted, published,
#' review_url, repository`, and `archive_doi`.
#'
#' @inheritParams rmarkdown::pdf_document
#' @param journal one of "JOSS" or"JOSE"
#' @param keep_md Whether to retain the intermediate markdown and images.
#'   Defaults to TRUE.
#' @param ... Arguments passed to [rmarkdown::pdf_document()]
#' @export
