Utilities for managing memory resources with cgroups

Memory management is an important consideration for a multi-user computing server, because if users collectively attempt to use more memory than is available on the system, it may crash. A useful means of preventing this is cgroups which can assign users to "control groups" which are limited to a given quantity of resources (such as CPU, disk, or memory usage).

However, cgroups are somewhat complicated to use in practice. mutil streamlines the memory management component.
