+functions supporting updates (listed with %, see note above) can be used like so:
+
+```lua
+obj = llib.crypto.adler32_init()
+llib.crypto.adler32_update(obj, "meow")
+local hash = llib.crypto.adler32_final(obj) --043c01b9
+
+--or you can chain them!
+obj = llib.crypto.adler32_init()
+obj:update("meow")
+hash = obj:final() --043c01b9s (the same)
+```

 all functions have 1 argument which is a string, unless noted otherwise
