-Spack is a package management tool designed to support multiple
-versions and configurations of software on a wide variety of platforms
-and environments. It was designed for large supercomputing centers,
-where many users and application teams share common installations of
-software on clusters with exotic architectures, using libraries that
-do not have a standard ABI. Spack is non-destructive: installing a new
-version does not break existing installations, so many configurations
-can coexist on the same system.
-
-Most importantly, Spack is simple. It offers a simple spec syntax so
-that users can specify versions and configuration options
-concisely. Spack is also simple for package authors: package files are
-written in pure Python, and specs allow package authors to write a
-single build script for many different builds of the same package.

+Spack offers a simple "spec" syntax that allows users to specify versions
+and configuration options. Package files are written in pure Python, and
+specs allow package authors to write a single script for many different

+*all* the ways you want to.
