%description
Make R scripts reproducible, by ensuring that every time a given script is
run, the same version of the used packages are loaded (instead of
whichever version the user running the script happens to have installed).
This is achieved by using the command groundhog.library() instead of the
base command library(), and including a date in the call. The date is used
to call on the same version of the package every time (the most recent
version available at that date). Load packages from CRAN, GitHub, or
Gitlab.
