+ # ### Some "standard" ENVs that multiple providers may set ###
+ #
+ # * CI - this is set by _most_ (but not all) CI providers now; it's approaching a standard.
+ # * CI_NAME - Not as frequently used, but some providers set this to specify their own name
+
+ # Any of these being set is a reasonably reliable indicator that we are
+ # executing in a CI environment.

+ # For each CI, this env suffices to indicate that we're on _that_ CI's
+ # containers. (A few of them only supply a CI_NAME variable, which is also
+ # nice). And if they set "CI" but we can't tell which one they are, we also
+ # want to know that - a bare "ci" without another token tells us as much.
