In ropenscilabs/blogyaml: Helps Editing Tags of Markdown Based Blog Posts

#' @param path path to where the posts are found
#' @title Shiny app for batch tag editing
#' @description Launch Shiny app for batch tag editing
#' @details The YAML metadata can also be edited in other fields, e.g. a slug
#' can become lala instead of 'lala' which should not pose any problem.
#' That said, do check all edits before committing them (assuming your website is
#'  under version control!).
#' @examples
#' \dontrun{
#'  blog_path <- system.file(package = "blogyaml", "example_blog")
#'  edit_tags(blog_path)
#'  }
