/* M2Sharp -- Modula-2 to C# Translator & Compiler
*
* Copyright (c) 2016 The Modula-2 Software Foundation
*
* Author & Maintainer: Benjamin Kowarsch <trijezdci@org.m2sf>
*
* @synopsis
*
* M2Sharp is a multi-dialect Modula-2 to C# translator and via-C# compiler.
* It supports the dialects described in the 3rd and 4th editions of Niklaus
* Wirth's book "Programming in Modula-2" (PIM) published by Springer Verlag,
* and an extended mode with select features from the revised language by
* B.Kowarsch and R.Sutcliffe "Modula-2 Revision 2010" (M2R10).
*
* In translator mode, M2Sharp translates Modula-2 source to C# source files.
* In compiler mode, M2Sharp compiles Modula-2 source via C# source files
* to object code or executables using the host system's C# compiler.
