  "Description": "Make R scripts reproducible, by ensuring that every time a\ngiven script is run, the same version of the used packages are\nloaded (instead of whichever version the user running the\nscript happens to have installed). This is achieved by using\nthe command groundhog.library() instead of the base command\nlibrary(), and including a date in the call. The date is used\nto call on the same version of the package every time (the most\nrecent version available at that date). Load packages from\nCRAN, GitHub, or Gitlab.",
