In usethis: Automate Package and Project Setup

#' Use "latest" versions of all dependencies
#'
#' Pins minimum versions of all `Imports` and `Depends` dependencies to latest
#' ones (as determined by `source`). Useful for the tidyverse package, but
#' should otherwise be used with extreme care.
#'
#' @keywords internal
#' @export
#' @param overwrite By default (`TRUE`), all dependencies will be modified.
#'   Set to `FALSE` to only modify dependencies without version
#'   specifications.
#' @param source Use "CRAN" or "local" package versions.
