+#
+# SYNOPSIS
+#   <item> [<item>...] [--from] <list>
+#   <item> [<item>...] --from <list1> [<list2>...]
+#
+# DESCRIPTION
+#   Erase any number of items from any number of lists. If more than one
+#   list is specified it must be separated from the items with --from.
+#
+# NOTES
+#   While items are basically any valid sequence of symbols, lists refer
+#   to any global variable or local variable in the scope of the calling
+#   function by name.
+#
