| 28 | + * |
| 29 | + * this dynamic loader uses the system dynamic loading interface for shared |
| 30 | + * libraries (ie. dlopen/dlsym/dlclose). The user must specify a shared |
| 31 | + * library as the file to be dynamically loaded. |

| 35 | + * begin with an underscore is fairly tricky, and some versions of |
| 36 | + * NetBSD (like 1.0, and 1.0A pre June 1995) have no dlerror.) |
