#
# Possible `options` are:
#
# `:force`
# :   forced operation (rewrite files if exist, remove directories if not empty,
#     etc.);
# `:verbose`
# :   print command to be run, in bash syntax, before performing it;
# `:preserve`
# :   preserve object's group, user and modification time on copying;
# `:noop`
# :   no changes are made (usable in combination with `:verbose` which will
#     print the command to run)
#
#
# Each method documents the options that it honours. See also ::commands,
# ::options and ::options_of methods to introspect which command have which
# options.
#
# All methods that have the concept of a "source" file or directory can take
# either one file or a list of files in that argument.  See the method
# documentation for examples.
#
# There are some `low level' methods, which do not accept keyword arguments:
#
#     FileUtils.copy_entry(src, dest, preserve = false, dereference_root = false, remove_destination = false)
#     FileUtils.copy_file(src, dest, preserve = false, dereference = true)
#     FileUtils.copy_stream(srcstream, deststream)
#     FileUtils.remove_entry(path, force = false)
#     FileUtils.remove_entry_secure(path, force = false)
#     FileUtils.remove_file(path, force = false)
#     FileUtils.compare_file(path_a, path_b)
#     FileUtils.compare_stream(stream_a, stream_b)
#     FileUtils.uptodate?(file, cmp_list)
#
# ## module FileUtils::Verbose
#
# This module has all methods of FileUtils module, but it outputs messages
# before acting.  This equates to passing the `:verbose` flag to methods in
# FileUtils.
#
# ## module FileUtils::NoWrite
#
# This module has all methods of FileUtils module, but never changes
# files/directories.  This equates to passing the `:noop` flag to methods in
# FileUtils.
#
# ## module FileUtils::DryRun
#
# This module has all methods of FileUtils module, but never changes
# files/directories.  This equates to passing the `:noop` and `:verbose` flags
# to methods in FileUtils.
