+## @deftypefn{Function File} {} get (d, key, defv)
+## Queries for the values of specified key(s). Unlike indexing, however,
+## this does not throw an error if a key is missing but rather substitutes
+## a default value. If @var{key} is a cell array, @var{defv} should be either
+## a cell array of the same shape as @var{key}, or a singleton cell.
+## Non-cell values will be converted to a singleton cell.
