/**

* @mainpage Cppcheck

* @version 2.10.99

* @section overview_sec Overview

* Cppcheck is a simple tool for static analysis of C/C++ code.

* When you write a checker you have access to:

* - %Token list - the tokenized code

* - Syntax tree - Syntax tree of each expression

* - %SymbolDatabase - Information about all types/variables/functions/etc

* in the current translation unit

* - Library - Configuration of functions/types

* - Value flow analysis - Data flow analysis that determine possible values for each token

* Use --debug-normal on the command line to see debug output for the token list

* and the syntax tree. If both --debug-normal and --verbose is used, the symbol

* database is also written.

* The checks are written in C++.

* @section detailed_overview_sec Detailed overview

* This happens when you execute cppcheck from the command line:

* -# CppCheckExecutor::check this function executes the Cppcheck

* -# CmdLineParser::parseFromArgs parse command line arguments

* - The Settings class is used to maintain settings

* - Use FileLister and command line arguments to get files to check

* -# ThreadExecutor create more instances of CppCheck if needed

* -# CppCheck::check is called for each file. It checks a single file

* -# Preprocess the file (through Preprocessor)

* - Comments are removed

* - Macros are expanded

* -# Tokenize the file (see Tokenizer)

* -# Run the runChecks of all check classes.

* When errors are found, they are reported back to the CppCheckExecutor through the ErrorLogger interface.
