subversion etiquette

[Rick Hillegas]

Sometime soon I hope to checkin some JUnit-based tests for testing the 
compatibility of our clients and servers. As part of this submission, I 
want to checkin the JUnit jar itself (into tools/java alongside the 
other jars). Is it ok for the svn diff to contain a big binary file like 
this? Will this annoy/confuse reviewers? Is there a more polite way to 
submit jar files?

Thanks,
-Rick
