Question: Visioo-writer supports document formats such as KWord, and this, an open-source word processor written in C++?

Context paragraphs:
C++ Standard Library: In the C++ programming language, the C++ Standard Library is a collection of classes and functions, which are written in the core language and part of the C++ ISO Standard itself.  The C++ Standard Library provides several generic containers, functions to utilize and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for everyday tasks such as finding the square root of a number.  The C++ Standard Library also incorporates 18 headers of the ISO C90 C standard library ending with ". h", but their use is deprecated.  No other headers in the C++ Standard Library end in ". h".  Features of the C++ Standard Library are declared within the codice_1 namespace.

Turbo C++: Turbo C++ is a discontinued C++ compiler and integrated development environment and computer language originally from Borland.  Most recently it was distributed by Embarcadero Technologies, which acquired all of Borland's compiler tools with the purchase of its CodeGear division in 2008.  The original Turbo C++ product line was put on hold after 1994 and was revived in 2006 as an introductory-level IDE, essentially a stripped-down version of their flagship C++Builder.  Turbo C++ 2006 was released on September 5, 2006 and was available in 'Explorer' and 'Professional' editions.  The Explorer edition was free to download and distribute while the Professional edition was a commercial product.  In October 2009 Embarcadero Technologies discontinued support of its 2006 C++ editions.  As such, the Explorer edition is no longer available for download and the Professional edition is no longer available for purchase from Embarcadero Technologies.  Turbo C++ is succeeded by C++Builder.

C++11: C++11 is a version of the standard for the programming language C++.  It was approved by International Organization for Standardization (ISO) on 12 August 2011, replacing C++03, superseded by C++14 on 18 August 2014 and later, by C++17.  The name follows the tradition of naming language versions by the publication year of the specification, though it was formerly named "C++0x" because it was expected to be published before 2010.

CodeSynthesis XSD: CodeSynthesis XSD is an XML Data Binding compiler for C++ developed by Code Synthesis and dual-licensed under the GNU GPL and a proprietary license.  Given an XML instance specification (XML Schema), it generates C++ classes that represent the given vocabulary as well as parsing and serialization code.  It is supported on a large number of platforms, including AIX, Linux, HP-UX, OS X, Solaris, Windows, OpenVMS, and z/OS.  Supported C++ compilers include GNU G++, Intel C++, HP aCC, Solaris Studio C++, IBM XL C++, and Microsoft Visual C++.  A version for mobile and embedded systems, called CodeSynthesis XSD/e, is also available.

Managed Extensions for C++: Managed Extensions for C++ or just Managed C++ is a now deprecated Microsoft set of deviations from C++, including grammatical and syntactic extensions, keywords and attributes, to bring the C++ syntax and language to the . NET Framework.  These extensions allowed C++ code to be targeted to the Common Language Runtime (CLR) in the form of managed code as well as continue to interoperate with native code.  Contrary to what many people say, Managed C++ was a complete standalone, or full-fledged programming language because its absolute possible to write a complete Managed C++ program, just like with any other . NET language.

Visioo-Writer: Visioo-writer - The OpenDocument file viewer is a computer program designed to run on multiple operating systems with the explicit ability to view OpenDocument and OpenOffice.org/StarOffice documents.  It is currently in a stable state (version 0.6) but updates continue.  The goal is to create a small application to open popular and free document formats (e.g., AbiWord, KWord).  The software is open source, and written in Python.  Downloads are available for Microsoft Windows and Linux.

C++ Technical Report 1: C++ Technical Report 1 (TR1) is the common name for ISO/IEC TR 19768, C++ Library Extensions, which was a document proposing additions to the C++ standard library for the C++03 language standard.  The additions include regular expressions, smart pointers, hash tables, and random number generators. TR1 was not a standard itself, but rather a draft document.  However, most of its proposals became part of the later official standard, C++11.  Before C++11 was standardized, vendors used this document as a guide to create extensions.  The report's goal was "to build more widespread existing practice for an expanded C++ standard library."

Herb Sutter: Herb Sutter is a prominent C++ expert.  He is also a book author and a columnist for Dr. Dobb's Journal.  He joined Microsoft in 2002 as a platform evangelist for Visual C++ . NET, rising to lead software architect for C++/CLI.  Sutter served as secretary and convener of the ISO C++ standards committee for over 10 years.  In September 2008 he was replaced by P.J. Plauger.  He then re-assumed the convener position, after Plauger resigned in October 2009.  In recent years Sutter was lead designer for C++/CX and C++ AMP.

Crypto++: Crypto++ (also known as CryptoPP, libcrypto++, and libcryptopp) is a free and open source C++ class library of cryptographic algorithms and schemes written by Wei Dai.  Crypto++ has been widely used in academia, student projects, open source and non-commercial projects, as well as businesses.  Released in 1995, the library fully supports 32-bit and 64-bit architectures for many major operating systems and platforms, including Android (using STLport), Apple (Mac OS X and iOS), BSD, Cygwin, IBM AIX and S/390, Linux, MinGW, Solaris, Windows, Windows Phone and Windows RT.  The project also supports compilation using C++03, C++11 and C++17 runtime libraries; and a variety of compilers and IDEs, including Borland Turbo C++, Borland C++ Builder, Clang, CodeWarrior Pro, GCC (including Apple's GCC), Intel C++ Compiler (ICC), Microsoft Visual C/C++, and Sun Studio.

AbiWord: AbiWord ( ) is a free and open-source software word processor written in C++.  Since version 3 it is based on GTK+ 3.  The name "AbiWord" is derived from the root of the Spanish word ""abierto"", meaning "open".
