Like this: > > --target-list=LIST set target list [] > Available targets: i386-softmmu ... > i386-linux-user ... The "[]" here is wrong, incidentally, because the bit in [] is supposed to be the default value, which for the target list is not "build no targets" but "build all targets". So we could either say: --target-list=LIST set target list (default: build everything) Available targets: i386-softmmu ... i386-linux-user ... or --target-list=LIST set target list [i386-softmmu ... i386-linux-user ...] I vaguely prefer the first but have no strong feelings. The other issue is that the target list is vastly longer than any of the existing lists in the help, so it probably needs something to automatically format it so it doesn't mess up the formatting of the --help message. (We could perhaps support --option=? for all the options that take a list, in addition to giving the supported values in --help, but maybe that's overkill.) -- PMM
