Erm, this depends on your CWD. If you're in src/, you just nuked
src/components...

I would make this script do a dry run by default and just print out what it
would delete/chomd. Only carry out the operations if ran with --really-do-this.

Fixed, scripts makes everything in its own directory now.
It is not so easy, because actions made by commands depend of results of
previous commands. For example, the command that removes empty directories from
web-animations-js.

+bower install
+find components/web-animations-js/ -type f \

For each of these find commands, how many files are actually affected. If it's
not too long, perhaps you want to be explicit about it?

Is the output of "bower install" always the same? It's a bit weird that this is
called "reproduce.sh" but I worry this may not always produce the same output.

~ 200 files in web-animations-js and 12 files in core-list. I think find
commands is more descriptive, then an explicit list.
 
Yes, it is. I've stated exact versions for every package
in bower.json and wrote presubmit script to be sure that we installed only
dependencies listed in bower.json.
