+ At this moment, all of them share the single "selecttab", which means their
+ namespaces are common, but they also have respective tables (attrtab,
+ opttab, etc.).
+
+ Selecting an option (addoption()), that is also a module name, works only if
+ the module doesn't depend on anything, because addoption() doesn't select
+ module and its dependencies (selectattr()). In other words, an option is
+ only safely converted to a module (define), only if it doesn't depend on
+ anything. (One example is DDB.)
