+package template and can use it to build variant packages at runtime.  Your
+variable package will export a subroutine which will build a variant package,
+combining its arguments with the template, and return the name of the new
+variant package.  The implementation does not care about what kind of packages
+it builds, be they simple function exporters, classes, singletons or something
+else.")
