debian source packages for python-rospkg, python-rosdep, etc
For most ROS .deb packages (e.g. for ros-hydro-ros), one can get the source by adding a "deb-src" line into the /etc/apt/sources.list with the same repository as the "deb" line. Then, one can download the source package files with something like:
apt-get source ros-hydro-ros
This will download the .orig.tar.gz, .dsc, and .debian.tar.gz file. So far so good. (And a great improvement from earlier versions of ROS.)
However, there are some packages for which the source cannot be downloaded this way. Where should I look for the source to packages such as python-rospkg, python-rosdep, python-vcstools, python-catkin-pkg, ps-engine and so on?
Also, I think it would be great if these were included in the same source repository as the rest of the packages.
