# 
# = ftools.rb: Extra tools for the File class
#
# Author:: WATANABE, Hirofumi
# Documentation:: Zachary Landau
#
# This library can be distributed under the terms of the Ruby license.
# You can freely distribute/modify this library.
#
# It is included in the Ruby standard library.
#
# == Description
#
# ftools adds several (class, not instance) methods to the File class, for
# copying, moving, deleting, installing, and comparing files, as well as
# creating a directory path.  See the File class for details.
#
# FileUtils contains all or nearly all the same functionality and more, and
# is a recommended option over ftools 
#
# When you
#
#   require 'ftools'
#
# then the File class aquires some utility methods for copying, moving, and
# deleting files, and more.
#
# See the method descriptions below, and consider using FileUtils as it is
# more comprehensive.
