+ (description
+ "This package provides a library called libpfm4, which is used to develop
+monitoring tools exploiting the performance monitoring events such as those
+provided by the Performance Monitoring Unit (PMU) of modern processors.
+
+Libpfm4 helps convert from an event name, expressed as a string, to the event
+encoding that is either the raw event as documented by the hardware vendor or
+the OS-specific encoding. In the latter case, the library is able to prepare
+the OS-specific data structures needed by the kernel to setup the event.
+
+libpfm4 provides support for the @code{perf_events} interface, which was
+introduced in Linux 2.6.31.")
