> It inherits its ros environment from your local environment and as
> such does not need /etc/roc/env to be configured.
> This is now launched as part of webui.launch.
> If you check out trunk of the web_interface stack, you might have more
> success getting that running.

> up gazebo with a pr2, roslaunch webui webui.launch and then go to
> http://localhost:8080, and successfully interface to the pr2 with the
> webui.
> The only environment variable it still makes use of at the moment is:
> "/etc/ros/env/ROBOT", to determine which apps to display.  I intend to
> switch this over to using a parameter from the parameter server,
> however, possibly by the end of the day.
> NOTE: trunk is not stable and I may be breaking things as I proceed.
> However, it may still be easier to work with than the existing
> mechanism of dealing with /etc/ros/env.  It may also provide guidance
> in getting an appropriate apache server running through a different
> mechanism.
> I will send out a more detailed email when I finish making all of my
> changes to the stack and releasing a new version of web_interface.
