%description
The book The Linux Programming Interface and training courses given by
man7.org are accompanied with a set of code examples. Some of these
examples are useful in their own right. This package includes the
following utilities.
- pid_namespaces  Show the PID namespace hierarchy.
- namespace_of	  Show the namespace memberships of one or more processes
		  in the context of the user or PID namespace
		  hierarchy. See the bundled source code for further
		  documentation.
- userns_overview Display a hierarchical view of the user namespaces
		  on the system along with the member processes for
		  each namespace.
- view_v2_cgroups Display one or more subtrees in the cgroups v2
		  hierarchy. The following info is displayed for each
		  cgroup: the cgroup type, the controllers enabled in
		  the cgroup, and the process and thread members of
		  the cgroup.
