# this  is  a  simple  script to  automate  publishing  a
# website generated by `tsunami`  to github pages. on its
# first  run  it will  ask  you  for some  authentication
# details,  initialize a  git repository,  and store  the
# parameters  you supply  there. on  subsequent runs,  it
# will push all changes to the repository.
