# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in. You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

${NAME}: libcgroup (library and utilities for kernel control groups)
${NAME}:
${NAME}: Control Groups provide a mechanism for aggregating/partitioning sets
${NAME}: of tasks, and all their future children, into hierarchical groups
${NAME}: with specialized behaviour.  It makes use of a filesystem interface.
${NAME}: This package contains a library for developing applications that use
${NAME}: control groups, as well as some basic userspace tools for controlling
${NAME}: and monitoring control groups.
