C/C++ Program Perfometer: Tool for measuring comparative performance of the C/C++ code

========= C/C++ Program Perfometer =========
############################################
The C/C++ Program Perfometer is a tool for measuring comparative performance of the C/C++ code.
=====================================
BRIEF DESCRIPTION
-----------------------------------
The Perfometer enables to get performance
of C/C++ program and separated pieces of the code for arbitrary metrics
(for instance : clocks, uclocks, rusage-metrics, metrics defined by user etc.).
The measurement results are represented in detailed/summary reports.
The detailed report holds results of individual tests,
the summary report holds average cost and its analysis.
The comparison results are represented in comparative tables
for separate comparison groups.
The user may set various parameters
in order to control the measurement/comparison process :
* measurement report and detailed measurement report flags,
* total tests,
* total repetitions,
* measurement scale,
* confidence threshold.
The Perfometer contains various testsuites for measuring comparative performance.
=====================================
LATEST RELEASE
Release 2.8.0-1.18
Note. Release number N1-N2 consists of :
* N1 : Version of C++ Perfometer itself; current version is 2.8.0,
* N2 : Version of Testsuites; current version is 1.18.
