comparison scripts/make.sh @ 1032:40d0c96a8e89 draft

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add scripts/single.sh to build individual non-multiplexed standalone commands. Alas, you can't quite do this yet: make defconfig make for i in $(./toybox) do echo $i PREFIX=singles/ scripts/single.sh $i || break done Because the OLDTOY() aliases for commands won't build without the base command. And I can't just skip them because chown/chmod or mv/cp aren't the same thing.
