[svn-r6007] Purpose:

Improvement
Description:
    Moved the code parsing for missing file name in the parse_command_line
    routine.
    Added a test checking if the tool fails as expected when no file name is
    given.
Platforms tested:
    Tested h5committest {arabica (fortran), eirene (fortran, C++)
	modi4 (parallel, fortran)}? YES
Misc. update:
    Update MANIFEST if you add or remove any file. YES, added nofilename.ddl
