      28             :  * When you write a checker you have access to:
      29             :  *  - %Token list - the tokenized code
      30             :  *  - Syntax tree - Syntax tree of each expression

      32             :  *    in the current translation unit
      33             :  *  - Library - Configuration of functions/types
      34             :  *  - Value flow analysis - Data flow analysis that determine possible values for each token
      35             :  *
      36             :  * Use --debug-normal on the command line to see debug output for the token list
      37             :  * and the syntax tree. If both --debug-normal and --verbose is used, the symbol
      38             :  * database is also written.

      45             :  * -# CmdLineParser::parseFromArgs parse command line arguments
      46             :  *   - The Settings class is used to maintain settings
      47             :  *   - Use FileLister and command line arguments to get files to check
      48             :  * -# ThreadExecutor create more instances of CppCheck if needed
      49             :  * -# CppCheck::check is called for each file. It checks a single file
      50             :  * -# Preprocess the file (through Preprocessor)
      51             :  *   - Comments are removed
      52             :  *   - Macros are expanded
      53             :  * -# Tokenize the file (see Tokenizer)
