I am pleased to announce the first release of Scion.

Scion [1] is a Haskell library that aims to implement those parts of a
Haskell IDE which are independent of a particular front-end.  Scion
is based on the GHC API and Cabal.  It provides both a Haskell API and
a server for non-Haskell clients such as Emacs and Vim.

Scion is bundled with two front-ends, Emacs and Vim, and is used by
the Haskell Eclipse plugin EclipseFP.  Work on Yi support is underway.

Scion's current features include:

  - Opening (that is, typechecking) a component of a Cabal project or a
    single file [Emacs, Vim]. Error messages are highlighted in the
    source [Emacs].

  - Saving a file automatically typechecks the file [Emacs, Vim].
    This feature can be turned off.

  - Look up the type of any identifier (even local variables) [Emacs,  
    Requires that the file typechecks.

  - Jump to definition of an identifier defined in the current project

For more details on the provided features and instructions of how to
set up a particular front-end see the README [2].

Patches are always welcome.  The main source repository is hosted on
Github [3].  If you find a problem please file a bug [4] and/or join
the developer's mailing list [5].
