A neophyte would have read the previous paragraph first.  The previous 
paragraph says specifically how to use test-wrapper for testing over SSH, 
then the proposed new paragraph says "In general,", and goes on to discuss 
how you might use a test-wrapper that isn't cross-test-ssh.sh and what the 
requirements are if writing your own wrapper.  I think the previous 
paragraph gives the required orientation.
