 Title: A Unifying API for Progress Updates
-Description: A minimal API for reporting progress updates upstream.  The design is to separate the representation of progress updates from how they are presented.  What type of progress to signal is controlled by the developer.  How these progress updates are rendered is controlled by the end user.  For instance, some users may prefer visual feedback such as a horizontal progress bar in the terminal, whereas others may prefer auditory feedback.
+Description: A minimal, unifying API for scripts and packages to report progress updates. By design, it allows the developer to focus on what progress that should be reported on, without having to worry about how to present it. The end user has full control on how, where, and when to render these progress updates, e.g. in the terminal using 'utils::txtProgressBar()' or 'progress::progress_bar()', in a graphical user interface using 'utils::winProgressBar()', 'tcltk::tkProgressBar()' or 'shiny::withProgress()', via the speakers using 'beep::beepr()', or on a file system via the size of a file. Anyone can add additional, customized, progression handlers. The 'progressr' package uses R's condition framework for signaling progress updated. Because of this, progress can be reported from almost anywhere in R, e.g. from classical for and while loops, from map-reduce APIs like the 'lapply()' family of functions, 'purrr', 'plyr', and 'foreach'. It will also work with parallel processing via the 'future' framework, e.g. 'future.apply::future_lapply()', 'furrr::map()', and 'foreach' with 'doFuture'.
