     48          <para>[ken] - Change the firefox instructions: stop recommending system
     49          ICU because the build fails with the current version, and change to
     50          using clang which saves build space (measurement is for 7.0, but 6.0 is
     51          good enough and smaller).</para>

     413      <option>./mach build -j4</option>: In theory, <command>mach</command>
     414      will use the number of online CPU cores - but on some machines the bulk
     415      of the build will drag on as if only 1 core is present. Specifying the
     416      number of jobs (4 in this example) fixes that.  Unlike traditional
     417      recommendations for running <command>make</command>, the exact number
     418      of cores is usually fastest - exceptionally, N+1 may be better on a
     419      well-specified modern machine. But do NOT use this if building from a
     420      term where <command>taskset</command> has been used to restrict the
     421      available cores.
