# Now, for the Jekyll part. There are some issues you might hit:
#
# * Due to jekyll/jekyll#3030 we need to detach Jekyll from the shell manually,
#   if we want --watch to work.
#
# * We need Vagrant >= 1.8 to fix a regression that botched emission of the
#   vagrant-mounted upstart event, see mitchellh/vagrant#6074 for details.
#
# * We need Ruby 2.1.7p400 due to what appears to be a regression in Ruby's
#   FileUtils core module, see http://stackoverflow.com/q/33091988
