#' Update Core of Personal Package

#' Updates the "core" of a personal package created with personalr. It can
#' either append another package to the current core or overwrite it
#' with a new core.

#' @param append If \code{TRUE} the packages of the argument \code{core} will
#'   be appended to the current core and the package version will be increased
#'   on the "patch" level. Otherwise \code{core} will be overwritten and the
#'   package version will be increased on the "minor" level.
