[ale] preferred pdf reader

[Todor Fassl]

I have a bit of a support problem. My end users are complaining about 
having to use evince for pdf files. They can't print half the time. I 
happen to be blind and the linux screen reader (orca) doesn't work well 
with any pdf viewer I've found.  Besides, I can't see what comes out on 
the printer. Is evince the best pdf program out there for linux? I was 
thinking I'd just install everything and let the end-users choose. Any 
suggestions as to what else I should try?
