#' Determine what operating system R is running under.

#' This code is adapted from a post discussing a safe way to
#' detect the operating system that R is running under:
#' https://www.r-bloggers.com/identifying-the-os-from-r/
#'
#' Specifically, this code is designed to return the proper operating
#' system name even if the R function 'Sys.info' is unimplemented.
