How can I pass options to a package? The options need to be available at package load time, as they refer to the name of library that is loaded.
One idea is for the user to define a variable, say `PACKAGE_OPTION="foo"`, prior to `using Package`, however I can't figure out how to then access the variable (or even determine if it is defined) from with the module. Any suggestions for how to do this, or an alternative approach? Simon
