Used to load the library LibraryName into the system if it has not already been loaded. The currently used Prolog suffix(es) is appended to LibraryName and the resulting library is loaded if it exists.
The search path used when loading libraries is specified by the global flag library_path using the get_flag/2 and set_flag/2 predicates. This flag contains a list of strings containing the pathnames of the directories to be searched when loading a library file. User libraries may be added to the system simply by copying the desired file into the ECLiPSe library directory. Alternatively the library_path flag may be updated to point at a number of user specific directories.
