- * Created: swmr_addrem_writer.c
- *
- * Purpose: Adds and removes data to a randomly selected subset of the
- * datasets in the SWMR test file.
- *
- * This program is intended to run concurrently with the
- * swmr_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 :)
