+## Preface
+
+Scala is a Java-like programming language which unifies
+object-oriented and functional programming. It is a pure
+object-oriented language in the sense that every value is an
+object. Types and behavior of objects are described by
+classes. Classes can be composed using mixin composition. Scala is
+designed to work seamlessly with two less pure but mainstream
+object-oriented languages – Java and C#.
+
+Scala is a functional language in the sense that every function is a
+value. Nesting of function definitions and higher-order functions are
+naturally supported. Scala also supports a general notion of pattern
+matching which can model the algebraic types used in many functional
+languages.
+
+Scala has been designed to interoperate seamlessly with Java.
+Scala classes can call Java methods, create Java objects, inherit from Java
+classes and implement Java interfaces. None of this requires interface
+definitions or glue code.
+
+Scala has been developed from 2001 in the programming methods
+laboratory at EPFL. Version 1.0 was released in November 2003. This
+document describes the second version of the language, which was
+released in March 2006. It acts a reference for the language
+definition and some core library modules. It is not intended to teach
+Scala or its concepts; for this there are [other documents](14-references.html).
+
+Scala has been a collective effort of many people. The design and the
+implementation of version 1.0 was completed by Philippe Altherr,
+Vincent Cremet, Gilles Dubochet, Burak Emir, Stéphane Micheloud,
+Nikolay Mihaylov, Michel Schinz, Erik Stenman, Matthias Zenger, and
+the author. Iulian Dragos, Gilles Dubochet, Philipp Haller, Sean
+McDirmid, Lex Spoon, and Geoffrey Washburn joined in the effort to
+develop the second version of the language and tools. Gilad Bracha,
+Craig Chambers, Erik Ernst, Matthias Felleisen, Shriram Krishnamurti,
+Gary Leavens, Sebastian Maneth, Erik Meijer, Klaus Ostermann, Didier
+Rémy, Mads Torgersen, and Philip Wadler have shaped the design of
+the language through lively and inspiring discussions and comments on
+previous versions of this document. The contributors to the Scala
+mailing list have also given very useful feedback that helped us
+improve the language and its tools.
