  # R_LIBS_SITE.  Ordinarily, it would be possible to make RStudio use
  # this same set of packages by simply overriding its version of R
  # with the wrapped one, however, RStudio internally overrides
  # R_LIBS_SITE.  The below works around this by turning R_LIBS_SITE
  # into an R file (fixLibsR) which achieves the same effect, then
  # uses R_PROFILE_USER to load this code at startup in RStudio.
