 16 With no subcommands given, 'perf check' comman    
 17 usage on the standard output.

 19 If the subcommand 'feature' is used, then stat    
 20 on the standard output (unless '-q' is also pa    
 21 compiled-in/built-in or not.

 23 is built-in, otherwise returns with exit statu

 30         Print whether feature(s) is compiled-i    
 31         exit status of 0, if passed feature(s)    
 32                                                   
 33         It expects a feature list as an argume    
 34         name/macro, or multiple features can a    
 35         list, in which case the exit status wi    
 36         features are compiled-in.                 
 37
