1. Go here: http://www.oracle.com/technetwork/topics/intel-macsoft-096467.html

6. Unzip instantclient-sqlplus and move its contents /opt/oracle/instantclient_11_2/

###
# A way to know, at runtime, what modules a module has used at compile time.
# In this case, you include `IndirectUsesTracker` into a module. When that module gets
# used in some other module, it makes that module registerable under a namespace of your choosing.
# When the registerable module is used into a third module, that third module will know at runtime which
# registerables were `use`d in it at compile time, via a function titled after the namespace.
