# Simple Web server to review HTML documentation.
#
# To use:
#
#   ./scripts/live &
#   open http://localhost:3000
#
# This server is necessary to test some behavior that only works when viewing
# the documentation over HTTP and fails when opening a file.  Specifically, it
# seems JavaScript cannot access external stylesheets when HTML is loaded from
# the file system.
