</span>Otherwise known as "a proper build system". glandium and co. have been<br>
working towards that for a long time. It's a big, difficult job. |mach<br>
build binaries| and |mach build faster| are temporary waypoints along<br>

common workflows. Eventually |mach build| should just do the right<br>
thing, no matter what files you've touched...<br>
