SUMMARY="libcg is a library that abstracts the control group file system in Linux"
DESCRIPTION="
libcgroup aims to provide programmers easily usable APIs to use the control group
file system. It should satisfy the following requirements:
- Provide a programmable interface for cgroups
- Provide persistent configuration across reboots
- Provide a programmable interface for manipulating configurations
