@ottobackwards I would be fine merging this in without running additional
testing like you've already done. What we cannot have though are the ASF
headers on source code we copied from elsewhere. You did a great job of adding
it to the NOTICE files but we cannot add the ASF header. Also, why can't we
just use the library as it exists as a binary dependency? Are there some
critical changes or something?---
