       Coz  is  a  new kind of profiler that unlocks optimization opportunities missed by traditional profilers.
       Coz employs a novel technique we call  causalprofiling  that  measures  optimization  potential.   This
       measurement matches developers' assumptions about profilers: that optimizing highly-ranked code will have
       the  greatest  impact  on  performance.  Causal  profiling  measures  optimization  potential for serial,
       parallel, and asynchronous programs without instrumentation of special handling  for  library  calls  and
       concurrency  primitives. Instead, a causal profiler uses performance experiments to predict the effect of
       optimizations. This allows the profiler to establish causality: "optimizing function X will  have  effect
       Y," exactly the measurement developers had assumed they were getting all along.

       --binary-scope<filepattern>, -b<filepattern>
              Profile  matching  executables.  Use  '%'  as a wildcard, or 'MAIN' to include the main executable
              (default=MAIN)

       --source-scope<filepattern>, -s<filepattern>
              Profile matching source files. Use '%' as a wildcard.  (default=%)

       --progress<sourcefile>:<linenumber>,-p<sourcefile>:<linenumber>
              [NOT SUPPORTED] Add a sampling-based progress point

       --output<profileoutput>, -o<profileoutput>
              Profiler output (default=`profile.coz`)

       --end-to-end
              Run a single performance experiment per-execution

       --fixed-line<sourcefile>:<linenumber>
              Evaluate optimizations of a specific source line

       --fixed-speedup<speedup>(0-100)
              Evaluate optimizations of a specific amount
