define Package/procps-ng/description
  procps is a set of command line and full-screen utilities that provide information out of the pseudo-filesystem
  most commonly located at /proc. This filesystem provides a simple interface to the kernel data structures.
  The programs of procps generally concentrate on the structures that describe the processess running on the system.

  NOTE: some utilities provided by procps-ng packages (ps, uptime, kill, ...) are installed as busybox applets, by default.
  Conflicting applets should be removed from the build to avoid file conflicts.
