When I also looked at the documentation for these packages, I could not
find any examples on how to use these:

http://www.iuma.ulpgc.es/users/jmiranda/gnat-rts/rts/g-dirope__ads.htm

When I write something myself, I try to always put a small example
at the top, as part of it documentation, of how to call or use it.
It would be nice if these had such examples.
