We can probably gamble that version 2 supports it so we could add some 
"or version > 2" to the test but indeed 'no standard on our machines' 
maans 'no testing' and no recent acrobat on our machines means 'no 
testing if a patch works either' ... no way we're going to subscribe to 
some monthly adobe service for tools we don't really need nor can afford 
to pay for the rest of our life just for the sake of maintaining free 
software.
