8 This class provides a configuration file and command line parser
9 for a tree-oriented configuration environment. All runtime configuration
12 Each configuration name is given as a fully scoped string such as
14 And has associated with it a text string. The Configuration class only
15 provides storage and lookup for this tree, other classes provide
16 configuration file formats (and parsers/emitters if needed).
18 Most things can get by quite happily with,
19 cout << _config->Find("Foo::Bar") << endl;
21 A special extension, support for ordered lists is provided by using the
22 special syntax, "block::list::" the trailing :: designates the
23 item as a list. To access the list you must use the tree function on
