The rmnlib-bin-extras_1.0_all SSM
package is used to override some of the installations already made in your repository. In
particular, the Um_set.dot script file from the base
env-utils_1.0_all package is replaced with a version that
is SSM-aware. This means that the order of installation of packages is important. If the
env-utils_1.0_all package is re-published for any (unlikely)
reason, then this package will have to be republished after it to ensure that
the override linking is done.
