+  A fork of the 'these' package without the dependency bloat
+description:
   This package provides a data type @These a b@ which can hold a value of either
   type or values of each type. This is usually thought of as an "inclusive or"
   type (contrasting @Either a b@ as "exclusive or") or as an "outer join" type
   (contrasting @(a, b)@ as "inner join").
