+ * 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.
