-        The HDF5 Library includes a predefined compression filter that

-        Precompiled Szip binaries for each supported platform and a source

-        Starting with release 1.6.3, Szip library binaries are distributed 
-        with the encoder enabled (a license may be required to use this binary) 
-        and with the encoder disabled (freely usable without a license). 
-        If the encoder enabled binary is used, Szip compression encoding is 
-        available for an HDF5 application; if the encoder disabled binary is 
-        used, Szip compression is not available.  Szip decoding is always 
-        available for applications (i.e., an HDF5 application can always read 
-        Szip-compressed data) if the Szip filter is present, regardless of the 
-        binary used.
+        Please notice that if HDF5 configure cannot find a valid Szip library,
+        configure will not fail; in this case, the compression filter will 
+        not be available to the applications.
+
+        To check if Szip compression was successfully configured in, 
+        check the "I/O filters (external):" line in the configure output,
+        summary section, printed to the standard output.
