comment = "Support for hardware performance counters"

desc = <<EOD
The Performance Counters Library (libpmc, -lpmc) provides a programming
interface that allows applications to use hardware performance counters
to gather performance data about specific processes or for the system as
a whole.  The library is implemented using the lower-level facilities
offered by the hwpmc(4) driver.

The utilities pmc(8), pmcannotate(8), pmccontrol(8) and pmcstat(8) provide
command-line access to the facilities provided by libpmc.
