Note that Mac OSX is really Unix (with an annoying point-and-click veneer
pasted on top of it) so you don't need to mess around with this ``open''
nonsense.  Just make ``filename'' executable.  Then you can do

 > system(filename)

Or if ``filename'' is not executable and you don't want to bother making
it so, do

 > system(paste("source",filename))

(That's the ***right*** --- i.e. Unix --- way of doing things.)
