/* gmt_mbsystem_glue.c populates the external array of this shared lib with
 * module parameters such as name, group, purpose and keys strings.
 * This file also contains the following convenience functions to
 * display all module purposes, list their names, or return keys or group:
 *
 *   int mbsystem_module_show_all    (void *API);
 *   int mbsystem_module_list_all    (void *API);
 *   int mbsystem_module_classic_all (void *API);
 *
 * These functions may be called by gmt --help and gmt --show-modules
 *
 * Developers of external APIs for accessing GMT modules will use this
 * function indirectly via GMT_Encode_Options to retrieve option keys
 * needed for module arg processing:
 *
 *   const char * mbsystem_module_keys  (void *API, char *candidate);
 *   const char * mbsystem_module_group (void *API, char *candidate);
 *
 * All functions are exported by the shared mbsystem library so that gmt can call these
 * functions by name to learn about the contents of the library.
