+Description: Emacs mode for editing Ur/Web programs
+ Ur is a pure, functional, statically typed, strict programming language in the
+ tradition of ML and Haskell; however, it features a significantly richer type
+ system.  Ur/Web is Ur plus a special standard library and associated rules for
+ parsing and optimization.  Ur/Web supports constructing dynamic web
+ applications backed by SQL databases.
+ .
+ This package provides an Emacs mode for editing Ur/Web source files.
