Further, in the warranty disclaimer both THE COPYRIGHT HOLDERS as well as ANYONE DISTRIBUTING THE SOFTWARE is protected from being liable for damages.Here is a copy of the MIT license.Copyright (C) <year> <copyright holders>Permission is hereby granted, free of charge, to any person obtaininga copy of this software and associated documentation files (theSoftware), to deal in the Software without restriction, includingwithout limitation the rights to use, copy, modify, merge, publish,distribute, sublicense, and/or sell copies of the Software, and topermit persons to whom the Software is furnished to do so, subject tothe following conditions:The above copyright notice and this permission notice shall beincluded in all copies or substantial portions of the Software.THE SOFTWARE IS PROVIDED AS IS, WITHOUT WARRANTY OF ANY KIND,EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OFMERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANYCLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT,TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THESOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.In contrast, the MIT license doesn't require the warranty disclaimer to be retained in all copies of the software and only the THE AUTHORS OR COPYRIGHT HOLDERS are protected from being liable for damages.It looks like the Boost Software License provides better protection against liabilities to anyone dealing with the software (even those who are simply distributing the software). Also, the Boost Software License makes it mandatory to reproduce the disclaimer in all copies.Why then does the author of the Boost license mention in http://ideas.opensource.org/ticket/45 that the Boost license does not extend the disclaimer of warranties to licensees, so that they may, if they choose, undertake such warranties (e.g., in exchange for payment)?
Boost Software License seems to extend disclaimer of warranty automatically but the author says it doesn't
