This file is public domain.

Sometimes people make changes to this file when it is a sub-module. If
you do so, the following incantation will create a branch called
'tmp', checkout the master, merge the tmp into the master, delete the
tmp branch, and push the results back to the origin:

git checkout -b tmp  ; git checkout master ; git merge tmp ; 
git branch -d tmp ; git push git@github.com:simsong/dfxml.git master
