- * Dynamic Loader on NetBSD 1.0.
- *
- * this dynamic loader uses the system dynamic loading interface for shared
- * libraries (ie. dlopen/dlsym/dlclose). The user must specify a shared
- * library as the file to be dynamically loaded.
- *
- * agc - I know this is all a bit crufty, but it does work, is fairly
- * portable, and works (the stipulation that the d.l. function must
- * begin with an underscore is fairly tricky, and some versions of
- * NetBSD (like 1.0, and 1.0A pre June 1995) have no dlerror.)
