#' @section Package options:

#' \emph{blastr} uses the following \code{\link{options}} to configure behaviour:
#'
#' \itemize{
#'   \item \code{blastr.blastdb.path}: Path to a local installation of the NCBI
#'   BLAST databases. By default this option is not set. I recommend setting it to
#'   a path of your choice in your .Rprofile file. Run \code{\link{update_blastdb}}
#'   to install these databases locally.
