 * \section intro_sec Technical overview
 * - Lightweight: It obtains the statistics directly from the system, nothing else is under it.
 * - Secure: it works with no privileges so no SUID bit is needed.
 * - Multi-architecture: it exposes a common API: common functions and common structures, most of the fields of these structures are common too, but not all of them. The OS-specific stuff has been reduced to the minimum.
 *
 * libsysactivity is made up of these feature sets:
 * - \ref src/common/cpu.h "cpu"
 * - \ref src/common/data_storage.h "data storage"
 * - \ref src/common/memory.h "memory"
 * - \ref src/common/network.h "network"
 * - \ref src/common/process.h "process"
