#' \describe{
#'   \item{\code{Seurat.memsafe}}{global option to call gc() after many operations.
#'   This can be helpful in cleaning up the memory status of the R session and
#'   prevent use of swap space. However, it does add to the computational overhead
#'   and setting to FALSE can speed things up if you're working in an environment
#'   where RAM availabiliy is not a concern.}
#'   \item{\code{Seurat.warn.umap.uwot}}{Show warning about the default backend
#'   for \code{\link{RunUMAP}} changing from Python UMAP via reticulate to UWOT}
#'   \item{\code{Seurat.checkdots}}{For functions that have ... as a parameter,
#'   this controls the behavior when an item isn't used. Can be one of warn,
#'   stop, or silent.}
