Catkin EmPY variables
I'm trying to create an env-hook for Catkin, and the common approach seems to be to use EmPY templates of shell scripts. I'm basically following the example of core/roslib/env-hooks.
The EmPY template seems to provide certain variables like @(ROS_DISTRO)
or @(CATKIN_DEVEL_PREFIX)
. Where can I find an overview over which variables are defined withing a Catkin EmPY template and how exactly are they defined?
