You can download gpsdings from its sourceforge project page.
The Sourceforge project page is also the place to submit bugs
and feature requests.
If you want to learn how to use gpsdings in practice have a look at the
detailed usage example.
There is also a list of free third party
software that I use together with gpsdings.
