# ==== Parameters
# destination<String>:: the relative path to the destination root.
# data<String|NilClass>:: the data to append to the file.
# config<Hash>:: give :verbose => false to not log the status.

# ==== Examples
#
# create_file "lib/fun_party.rb" do
# hostname = ask("What is the virtual hostname I should use?")
# "vhost.name = #{hostname}"
# end
#
# create_file "config/apache.conf", "your apache config"
