+    Loading the \emph{extended} set requires a tad more effort, but
+    it’s well invested.
+
+    Since we only want the functionality, we have to simulate parts
+    of a running \CONTEXT environment, above all logging, that some
+    of the more involved libraries cannot be loaded without.
+    Also, one utility file cannot be packaged because it returns a
+    table which would preclude loading of later code.
+    Thus, we remove it from the natural loading chain (it is not
+    critical) and append it at the end.
