require 'thor/actions/empty_directory'
class Thor
module Actions
# Copies recursively the files from source directory to root directory.
# If any of the files finishes with .tt, it's considered to be a template
# and is placed in the destination without the extension .tt. If any
# empty directory is found, it's copied and all .empty_directory files are
# ignored. Remember that file paths can also be encoded, let's suppose a doc
# directory with the following files:
#
# doc/
# components/.empty_directory
# README
# rdoc.rb.tt
# %app_name%.rb
#
# When invoked as:
#
# directory "doc"
#
# It will create a doc directory in the destination with the following
# files (assuming that the app_name is "blog"):
#
# doc/
# components/
# README
# rdoc.rb
# blog.rb
#
# ==== Parameters
# source<String>:: the relative path to the source root.
# destination<String>:: the relative path to the destination root.
# config<Hash>:: give :verbose => false to not log the status.
# If :recursive => false, does not look for paths recursively.
#
# ==== Examples
#
# directory "doc"
# directory "doc", "docs", :recursive => false
#
