+# Formal Parameters:
+# $cmd - The command request that got us dispatched.
+# $tail - The tail of the command. In this case this is a colon separated
+# set of values that will be split into:
+# $cdom - The LON-CAPA domain of the course.
+# $action - Either: clutter or declutter
+# clutter adds character(s) to eliminate ambiguity
+# declutter removes the added characters (e.g., for
+# display of the institutional course section string.
+# $info - A frozen hash in which keys are:
+# LON-CAPA course number:Institutional course code
+# and values are a reference to an array of the
+# items to modify -- either institutional sections,
+# or institutional course sections (for crosslistings).
+# $client - The socket open on the client.
+# Returns:
+# 1 - continue processing.
