# This method returns the full paths to all children-directories (i.e. first generation of descendants)
# of a directory in either an +Array+, or in a block.
#
# ==== Examples
#
# Dir.directories('/home/user') # => ['/home/user/Desktop', '/home/user/Documents', ...]
#
# Dir.directories('/home/user') do |dir|
# puts dir
# end
#

next unless child.directory?

end

# Converts a Pathname object into a +String+ and wraps it into two quotation
# marks (according to the +String#enquite+ method). This method is useful for
# printing a path in a readable way in a command-line user interface.

# Verifies whether the current directory (i.e. +pwd+) is the path of this Pathname
# object. Returns +true+ or +false+.
#
# ==== Examples
#
# Dir.chdir('/home/user')
# Pathname.new('/home/user').current_path? # => true
# Pathname.new('/home/user/../user').current_path? # => true
# Pathname.new('/lib').current_path? # => false
# Pathname.new('/i/do/not/exist').current_path? # => false
