I am sad to hear that. Not outputting the commands executed is one of 
the things I most appreciate about BB. Always when I see the output that 
is generated by compilation of a project that uses the autotools makes 
want run away and scream in horror. 5 to 15 lines of output (especially 
when using gettext) for each file compiled that scrolls by so fast and 
so unexpectedly causes that it takes me an awful lot of time just to 
figure out the name of the file being compiled. If the command works, I 
do not really care about all the options. I just want to know what is 
happening (compiling, linking... name of the files involved etc).

Can we have at least an option (command line or rule to put in Jamroot) 
to retain the current style of output? Thanks.
