+ * Purpose: Create a dataset compressed with the deflate filter.
+ * This program is used to create the test file `tdeflate.h5' which has
+ * a dataset compressed with the "deflate" I/O filter. This dataset will
+ * be used to verify the correct behavior of the library when a filter is
+ * not available for a dataset which requires it.
