I asked about this on the forums but never got an answer. I can't find any easy way to list what packages depend on what. npm has this with npm ls, and a similar solution could be done here
My solution, and I'm not even sure if it gets everything, is this
grep -r 'Package.blaze' .meteor/local/build/programs/web.browser/packages
If this is the best way, it would be nice if this were wrapped up in the tool with something like
meteor ls blaze
Or it could be more verbose and be list-dependencies
