[svn-r8904] Purpose:
h5diff and h5repack changes Description: h5diff introduced the following four modes of output: Normal mode: print the number of differences found and where they occured Report mode: print the above plus the differences Verbose mode: print the above plus a list of objects and warnings Quiet mode: do not print output (h5diff always returns an exit code of 1 when differences are found) h5repack added an extra parameter for SZIP filter (coding method) the new syntax is -f SZIP=<pixels per block,coding> (pixels per block is a even number in 2-32 and coding method is 'EC' or 'NN') Example of use: ./h5repack -i file1 -o file2 -f SZIP=8,NN -v updated usage messages, test scripts and files accordingly Solution: Platforms tested: linux AIX solaris Misc. update:
