+@itemize
+@item It supports a fuller range of emojis, including all those supported by
+GitHub
+@item It supports lookup of emoji aliases from emoji
+@item It uses Text rather than String
+@item It has a lighter dependency footprint: in particular, it does not
+require aeson
+@item It does not require TemplateHaskell
