.SH DESCRIPTION
.sp
.LP
The functions in this library traverse the lgroup (locality group) hierarchy,
discover its contents, and set a thread's affinity for an lgroup. A locality
group represents the set of CPU-like and memory-like hardware devices that are
at most some locality apart from each other.
