# 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.
