#' Lint all source files in a package.
#'
#' The default linters correspond to the style guide at
#' <http://r-pkgs.had.co.nz/r.html#style>, however it is possible to
#' override any or all of them using the `linters` parameter.
#' @template devtools
#' @param cache store the lint results so repeated lints of the same content
#' use the previous results.
#' @param ... additional arguments passed to [lintr::lint_package()]
#' @seealso [lintr::lint_package()], [lintr::lint()]
#' @details
#' The lintr cache is by default stored in `~/.R/lintr_cache/` (this can
#' be configured by setting `options(lintr.cache_directory)`).  It can be
#' cleared by calling [lintr::clear_cache()].
