Identifies global ("unknown" or "free") objects in R expressions
    by code inspection using various strategies (ordered, liberal,
    conservative, or deep-first search). The objective of this package is to
    make it as simple as possible to identify global objects for the purpose
    of exporting them in parallel, distributed compute environments.
