Setting for external programs?

[Aaron Hsu]

Perhaps I am missing this in the manuals, but I cannot figure out what I
need to do to reconfigure Gnus to open attachments with certain select
other programs. I would prefer to do this on some attachments rather
than saving the attachments to a temporary folder before viewing, and
subsequently deleting them. 

Would any be so kind as to explain the necessaries for me?
