/**
 *
 * @mainpage Cppcheck
 * @version 1.63.1
 *
 * @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 = Information about functions
 *
 * Use --debug on the command line to see debug output for the token list
 * and the syntax tree. If both --debug and --verbose is used, the symbol
 * database is also written.
 *
 * The checks are written in C++. The checks are addons that can be
 * easily added/removed.
 *
 * @section writing_checks_sec Writing a check
 * Below is a simple example of a check that detect division with zero:
 * @code
void CheckOther::checkZeroDivision()
{
    // Iterate through all tokens in the token list
    for (const Token *tok = _tokenizer->tokens(); tok; tok = tok->next())
    {
        if (Token::Match(tok, "/ 0"))
            reportError(tok, Severity::error, "zerodiv", "Division by zero");
    }
}
 @endcode
 *
 * The function Token::Match is often used in the checks. Through it
 * you can match tokens against patterns. It is currently not possible
 * to write match expressions that uses the syntax tree, the symbol database,
 * nor the library. Only the token list is used.
 *
 * @section checkclass_sec Creating a new check class from scratch
 * %Check classes inherit from the Check class. The Check class specifies the interface that you must use.
 * To integrate a check class into cppcheck all you need to do is:
 * - Add your source file(s) so they are compiled into the executable.
 * - Create an instance of the class (the Check::Check() constructor registers the class as an addon that Cppcheck then can use).
 *
 *
 * @section embedding_sec Embedding Cppcheck
 * Cppcheck is designed to be easily embeddable into other programs.
 *
 * The "cli/main.cpp" and "cli/cppcheckexecutor.*" files illustrate how cppcheck
 * can be embedded into an application.
 *
 *
 * @section detailed_overview_sec Detailed overview
 * This happens when you execute cppcheck from the command line:
 * -# CppCheckExecutor::check this function executes the Cppcheck
 * -# CppCheck::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.
 * -# Simplify the tokenlist (Tokenizer::simplifyTokenList)
 * -# Run the runSimplifiedChecks of all check classes
 *
 * When errors are found, they are reported back to the CppCheckExecutor through the ErrorLogger interface
