    Referesh performance testing framework
    
    Streamline it's operation, make it possible to easily reuse the system for
    other projects.

 ===================================
 
 This directory contains a framework to track performance development of a set

-Take a look at the top of Makefile for configuration of number of revisions to
-test. And just type make to build, later invokations of make when the
-repository has changed will generate tests for the new revisions. To re-run the
-last revision type 'make retry'.
+Type "make" to update a report of the performance over the last N revisions,
+where N is defined in the top of Makefile along with some other configuration

+An internal shallow clone of the master git repo is created for testing, when
