 \begin{abstract}
-We describe the Einstein Toolkit, a community-driven, freely accessible
-computational infrastructure intended for use in numerical relativity,
-relativistic astrophysics, and other applications.  The Toolkit, developed by a
-collaboration involving researchers from several institutions in the United
-States and others around the world, combines all of the components needed to
-simulate astrophysical objects including black holes, compact objects, and
-collapsing stars, as well as a full suite of analysis tools.  It is based on
-commonly used packages, such as the Cactus Framework for HPC computing and  the
-Carpet adaptive mesh refinement driver, but is under continuous development and
-contains many new code components that have been publicly released for the
-first time.   We discuss the motivation behind the release of the toolkit, the
-philosophy underlying its development, and the goals of the project.  A brief
-summary of numerical techniques is included, as are results of numerical test
-covering a variety of sample astrophysical problems.  We conclude with a
-discussion of future directions in which the toolkit is likely to be expanded.
+We describe the Einstein Toolkit, a community-driven, freely
+accessible computational infrastructure intended for use in numerical
+relativity, relativistic astrophysics, and other applications.  The
+Toolkit, developed by a collaboration involving researchers from
+several institutions around the world, combines a core set of
+components needed to simulate astrophysical objects including black
+holes, compact objects, and collapsing stars, as well as a full suite
+of analysis tools.  The Einstein Toolkit is based on the Cactus
+Framework for high-performance computing and the Carpet adaptive mesh
+refinement driver. It implements spacetime evolution via the BSSN
+evolution system and general-relativistic hydrodynamics in a
+finite-volume discretization. The toolkit is under continuous
+development and contains many new code components that have been
+publicly released for the first time and are described in this
+article.  We discuss the motivation behind the release of the toolkit,
+the philosophy underlying its development, and the goals of the
+project.  A summary of the implemented numerical techniques is
+included, as are results of numerical test covering a variety of
+sample astrophysical problems.
