The output above is not consistent with what maven 1 produces when jars 
are deployed using maven 1's jar goal, nor is it consistent with what 
md5sum -b produces or expects when used to verify.

This was recently discussed on commons-dev 
<http://marc.theaimsgroup.com/?t=113487309500001&r=1&w=2>, where the 
consensus appeared to be to use the format produced by md5sum -b for 
.md5 files included in releases:

<hash> *<file_name>

 From Carlos' reply, I assume maven (2?) can "eat" the format above when 
verifying jars.  Whatever we agree on, maven should be able to produce 
it as part of jar deployment as well, and we should probably use the 
same format for md5's attached to zips and tarballs.  My preference 
would be to use a "standard" format if such a thing exists.  Apologies 
if the format above is a standard and I am just ignorant of it.
