It should read like this: GNU `make' knows how to build several targets at once. Normally, `make' will build only one target at a time, waiting for it to finish before building the next. However, the `-j' or `--jobs' option tells `make' to build many targets simultaneously. dj> Maybe mention that this shows equivalence with sleep tests: dj> $ f=$SECONDS;make -j x y;expr $SECONDS - $f dj> $ f=$SECONDS;make x& make y& wait;expr $SECONDS - $f dj> But wait, that is only if x and y don't have any dependencies. I fail to see how this is in any way enlightening. -- ------------------------------------------------------------------------------- Paul D.
