Functions exist to check if source files are still C<good to use> as well as update them, and then parse them. The flow looks like this: $cb->_author_tree || $cb->_module_tree $cb->_check_trees $cb->__check_uptodate $cb->_update_source $cb->__update_custom_module_sources $cb->__update_custom_module_source $cb->_build_trees ### engine methods { $cb->_init_trees; $cb->_standard_trees_completed $cb->_custom_trees_completed } $cb->__create_author_tree ### engine methods { $cb->_add_author_object } $cb->__create_module_tree $cb->__create_dslip_tree ### engine methods { $cb->_add_module_object } $cb->__create_custom_module_entries $cb->_dslip_defs =head1 METHODS =cut =pod =head2 $cb->_build_trees( uptodate => BOOL, [use_stored => BOOL, path => $path, verbose => BOOL] ) This method rebuilds the author- and module-trees from source.
