That is just lazy hackery, please use the regular option library to add options and document them! Also, '--version2' is a sloppy name, the right solution is to do what Git does, it has a --build-options sub-option to 'perf version': triton:~/tip> git version -h usage: git version [<options>] --build-options also print build options triton:~/tip> git version --build-options git version 2.14.1 sizeof-long: 8 This should be done for perf as well, and _then_ maybe can we add a helper alias that maps '-vv' to 'version --build-options'. Thanks, Ingo
