Not sure what you mean by packages, but if you mean nested functions in
table structures. Then you can just create a table.
Registering takes a table with names and values. The values can also be
sub-tables, just push a table on the stack.

See https://github.com/Tieske/LuaUPnP/blob/master/lib_src/LuaUPnP.c#L1073
here it creates an 'UPnP' table with three subtables; 'web', 'http', 'util',
and then registers a list of c functions in each of those.
