+      Em is a QMC variant of the standard Unix text editor - ed. It includes all
+      of ed, so the documentation for ed is fully applicable to em. Em also has
+      a number of new commands and facilities designed to improve its
+      interaction and increase its usefulness to users at fast vdu terminals
+      (such as the ITT's at QMC).
