Does the Javascript package manager provide a simple way to reject
nonfree dependencies?  If it does not, this could be a real can of
worms.  We should not recommend the use or installation of a grammar
whose build procedure uses nonfree software, and if the package manager
doesn't give us an easy way to check that, we need to vet these grammars
one by one.
