Jack Lucchetti's "yahoo_get" function package (or the server) would be a
good place to look first for an example of accessing a website and
downloading data via hansl.

Off the bat, I don't think it would work to include a command line program
in a function package. For one thing, how would it be included in an XML
file? For another, function packages are intended to be cross-platform and
only dependent on gretl itself (though I guess we could make an exception
for a dependency on third party programs that are themselves available in
gretl-friendly forms for all platforms, such as X13as.)
