#dailyoneliner - find targets affected by the files you're changing
Maybe there's a better way, but this works for me...
g4 whatsout | perl -pe 's,^.*google3,/,; s,/([^/]+)$,:,' | xargs blaze-bin/devtools/deps/depserver/query/depends_on -ds
You can then expand this to do other useful things:
| xargs blaze build
to build affected targets
| xargs unused_deps
to find unused deps
