I was thinking of doing something small like a docker instance that can run `broctl check` using a mounted host directory. My questions are:

bro supports a '-a' option for validating syntax on scripts. I've built integration for it inside syntastic for vim and wrote an atom linter for bro, adding support for other editors is pretty easy.
Aside from that we don't bother.. if a broken script ends up getting pushed out somehow, broctl deploy will complain and we can fix it without ever impacting the running bro instances.

Specifically, /bro/bin/broctl wasn't functional until I installed python, but after running `apt-get update && apt-get install -y python && /bin/bro/broctl install` things seemed to be functional.
Ah.. I build those images for try.bro.org and for script testing (there's one for each version of bro) but I've never actually used them to run bro via broctl. You're probably better off just using it to run your scripts against a pcap.
