[ros-users] read parameter in launch file

[Axelrod, Benjamin]

Is there any way to read a parameter in a launch xml file?  For example,
I set the value of a parameter at the top of the file, then lower in the
file I read the parameter and use it for something.  Or must this type
of thing be done through environment variables?  If so, this seems like
a strange restriction.  Is there any reasoning behind this?
