[ros-users] Digital Camera 1394 in ROS?

This raises a bit of a issue I've had and I know students have when
looking for packages to achieve a task.

If I search for '1394' I get 6 results, if I search for 'camera' I get
47 results and none of these include the Brown probe package (since it
must not include these key words?). While the search mechanism allows
people to see what exists it offers little advice on what package to
select. In reality we have to pick based on the rough description
given by the developer, for example, what is the difference between
usc_cameradc1394 and cameradc1394 ? If we make the wrong decision,
then we may waste substantial time trying to integrate the wrong

As the number of packages grows we are going to see many duplicate
packages basically doing the same thing (maybe with a few small custom
modifications). Without an imposed minimum level of documentation
users will be swamped with uninformative search results. I know nobody
likes documentation, but as soon as we face 'search result spam' the
likelihood of us all becoming frustrated and just re-implementing our
own packages increases.
