Doing so is unsafe and could allow # malicious input to execute arbitrary code inside your application. Please see # doc/security.rdoc for more information. # # == History # # Syck was the original for YAML implementation in Ruby's standard library # developed by why the lucky stiff. # # You can still use Syck, if you prefer, for parsing and emitting YAML, but you # must install the 'syck' gem now in order to use it. # # In older Ruby versions, ie. <= 1.9, Syck is still provided, however it was # completely removed with the release of Ruby 2.0.0. # # == More info # # For more advanced details on the implementation see Psych, and also check out # http://yaml.org for spec details and other helpful information. # # Psych is maintained by Aaron Patterson on github: https://github.com/tenderlove/psych # # Syck can also be found on github: https://github.com/tenderlove/syck module YAML end
