Suppress superfluous output?

[GoogleCodeExporter]

I'm using ebpubcheck as a command line tool in a script, piped as follows:

/usr/bin/java -jar /opt/epubcheck/epubcheck.jar /path/to/file.epub 2>&1

The issue I'm having is that, even when a book is valid, there will be output.

Right now I grep for "check finished with warnings or errors" but I would 
prefer a command line option. Something that would instruct the app to return 
absolutely nothing if an epub is valid. Something like --noout in xmllint.

Is this possible?

Thank you for consideration.

Dear errors,
this is a good suggestion. We will add this in a release following the 
very-soon-now 3.0 release.

Revision 459 adds a -q or -quiet argument so that no message is sent to stdout, 
only errors are output to stderr
