        '/proc/cpuinfo' file, that is the source of the information provided by this
        class. The 'man lscpu(1)' also has information about a program that uses
	the '/proc/cpuinfo' file.

	Using this class one can obtain the number of CPUs in a system:

	  >>> cpus = procfs.cpuinfo()
          >>> print cpus.nr_cpus
          4

	It is also possible to figure out aspects of the CPU topology, such as
	how many CPU physical sockets exists, i.e. groups of CPUs sharing components
	such as CPU memory caches:

	  >>> print len(cpus.sockets)
	  1

	Additionally dictionary with information common to all CPUs in the system is
	available:

	  >>> print cpus["model name"]
          Intel(R) Core(TM) i7-3667U CPU @ 2.00GHz
          >>> print cpus["cache size"]
          4096 KB
          >>>

	Representation of an mmap in place for a process. Can be used to figure
	out which processes have an library mapped, etc.

	The 'perm' member can be used to figure out executable mmaps, i.e. libraries.

	The 'vm_start' and 'vm_end' in turn can be used when trying to resolve
	processor instruction pointer addresses to a symbol name in a library.
