       Usage: niccc [-dup] [-nodata] streamspec
    
    A program for conducting certain NIML tests 
    on input from streamspec and write the results to stderr
    
    Example:
        niccc file:Something.niml 
    
    Mandatory arguments:
       streamspec: A string defining a NIML stream.
    
    Options:
       -dup: Duplicate the element before showing it.
             This is to test NI_duplicate function.
       -nodata: Show header parts only in output
       -attribute ATTR: Dump the value of attribute ATTR
       -match MATCH: If MATCH is exact, then attribute name
                     is matched exactly. If MATCH is partial,
                     then a match of all the characters in ATTR
                     is enough. For example, an ATTR of COEF would
                     match any of COEF COEF.1 COEF.2, etc.
                Default is -match exact
       -f: streamspec is a filename.
       -s: streamspec is an element string like: 
                '<T font=9 coords="2.3 23 2"/>'
       -stdout: write elements to stdout, instead of stderr
       -#: put the # at the beginning of lines with no data
       -quiet: quiet stderr messages, and don't echo attribute
               name with -attribute option
       -find_nel_with_attr ATTR ATTRVAL: Only output elements 
                   that have an attribute ATTR of value ATTRVAL.
                   a status of 1 is returned if no match is found.
       -skip_nel_with_attr ATTR ATTRVAL: Do not output elements 
                   that have an attribute ATTR of value ATTRVAL.
       niccc returns a status of 0 if it the stream opened.
             and there were no interruptions.
