 ## Which DLLs were dynamically loaded by packages?
 library.dynam()
+## More on library.dynam.unload() :
+\donttest{require(nlme)
+nlme:::.onUnload # shows library.dynam.unload() call
+detach("package:nlme")  # by default, unload=FALSE ,  so,
+tail(library.dynam(), 2)# nlme still there
+## How to unload the DLL ?
+## Best is to unload the namespace,  unloadNamespace("nlme")
+## If we need to do it separately which should be exceptional:
+pd.file <- attr(packageDescription("nlme"), "file")
+library.dynam.unload("nlme", libpath = sub("/Meta.*", '', pd.file))
+tail(library.dynam(), 2)# 'nlme' is gone now
+unloadNamespace("nlme") # now gives warning
