-- | Check your cabal packages for lagging dependencies.
--   
--   This provides a library and command line tool for checking if the
--   upper bounds in your package's dependency list excludes the newest
--   package available. The code was originally available only as a web
--   interface at <a>http://packdeps.haskellers.com/</a>, but is now
--   available for standalone use as well.
--   
--   The command line tool has an incredibly simple interface: simply pass
--   it a list of cabal files, and it will tell you what dependencies- if
--   any- are restricted.

-- | The newest version of every package.

-- | Whether or not a package can accept all of the newest versions of its
--   dependencies. If not, it returns a list of packages which are not
--   accepted, and a timestamp of the most recently updated package.
