[ros-users] Screengrab/capture node

[William Woodall]

+1 neat!

We have two sort of "package lists", the first is the documentation list,
which will collect meta information from your package.xml (you should
double check the information is correct in your package.xml first) and
create for you a wiki page header. I would recommend grabbing a wiki page
for your package:

http://wiki.ros.org/screengrab_ros

And then following the instructions for getting a doc job running:

http://wiki.ros.org/rosdistro/Tutorials/Indexing%20Your%20ROS%20Repository%20for%20Documentation%20Generation

The other sort of package list we have is the released packages list, which
will build your package into debians for our supported platforms so it is
easier for others to get your package. You can do this by releasing your
package into hydro, which is detailed in the bloom tutorials:

http://wiki.ros.org/bloom

Both of these are optional.

Thanks for the contribution!
