+ * Created:     swmr_remove_writer.c
+ *
+ * Purpose:     Removes data from a randomly selected subset of the datasets
+ *              in the SWMR test file.
+ *
+ *              This program is intended to run concurrently with the
+ *              swmr_remove_reader program.  It is also run AFTER a sequential
+ *              (not concurrent!) invoking of swmr_writer so the writer
+ *              can dump a bunch of data into the datasets.  Otherwise,
+ *              there wouldn't be much to shrink :)
