# \donttest{
if (identical(Sys.getenv("OSRM_EXAMPLES"), "true")) {
  # Clean up a temporary project's .Rprofile
  old <- setwd(tempdir())
  on.exit(setwd(old), add = TRUE)
  writeLines(
    c(
      "#added-by-r-pkg-osrm.backend",
      'Sys.setenv(PATH = paste("dummy", Sys.getenv("PATH"), sep = .Platform$path.sep))'
    ),
    ".Rprofile"
