To load a file and all its dependencies, the advised solution is to define a +_loader_ file that loads all the necessary files for an application. A loader file is simply a source file, typically named `loader.lgt`, that makes calls to the `logtalk_load/1-2` +built-in predicates, usually from an `initialization/1` directive for portability and +standards compliance.
