 The jars are not installed to `/usr/share/java/` yet, but I copied them
 over for testing.  Once everything works I'm planning to ask our sysadmin
 to install them.  But the jars should be present:

 {{{

 providers-1.1.2.jar
 }}}

 Hmm, nothing in `onionoo-all.log`.  Weird.  Do you have an example of what
 should be logged?

 Fine question.  (I don't have a good answer yet.)

 Understood.  Makes sense!
