Comment:

 Hello

 I'd have few minor details:

 By „Assign “pg” to CXXFLAGS“ you mean CXXFLAGS='-pg'? Did the dash get
 eaten by wiki formatting?

 The diff output would be better as unified diff, to see the context around
 it. This way, if we change the source file of boss, the line numbers might
 get wrong.

 Does your system really have a capital 'G' in 'Gprof'? Mine is with
 lowercase, so I believe this could be a result of some editor automatic
 correction, or something like that.


 With regard to the profiling variables being in boss, I don't really like
 that. And I don't think an ordinary user ever wants to do profiling, if
 someone wanted to do that, he would be a developer already and editing a
 little bit of code shouldn't be a big problem.

 I thought of a different way to handle this. The file is saved to the
 current directory where the program exits. Maybe having a different
 directory to run in for each of the processes would be helpful. But
 changing the directories has the same problem as changing the environment,
 we are adding support for profiling when most users don't want it.

 Thank you
