Thanks James. With your help a bit more tinkering enabled me to find
the solution. I shouldn't be calling linkPath:toPath:, but
createSymbolicLinkAtPath:pathContent: instead to create aliases. With
that call, creating the alias is easy peasy. I list the corrected and
expanded complete method here in case it's of any use to anybody.
Note that this code only looks in the user's library folder, it
ignores the option of installing the service for all users.
