rename/order license properties better reflect how licenses work and are structured grant (permissions) conditioned on (conditions) with limitations Permissions coming first combats mistaken but apparently widespread impression that licenses impose conditions, even such that without a license, there would be no conditions/work would be in the public domain. Requirements->Conditions emphasizes that they are pertinent if one wants to take advantage of permissions. Forbiddens->Limitations is more accurate: in most cases licenses don't give permission to hold licensors liable, in some cases to use licensors' trademarks or patents, but a licensee does not lose the permissions granted by the license if the licensee holds licensor liable, etc. Also emphasizes that there are limitatations on the license grant, not that the license imposes prohibitions. The most concise place to see both the rename and reorder is in _includes/license-overview.html I did not reorder the appearance of the groups of properties in license source files (.txt files in _licenses) as those orderings are not used to render anything on the webiste. Might do so later. 2016-03-01 13:33:15 -08:00			`permissions:`

BSD licenses: bring back the list bullets 2013-07-19 03:15:18 +02:00			`* Redistributions of source code must retain the above copyright notice, this`
licenses: pre-format bsd license texts The license text is shown as preformatted text; therefore we need to wrap it to a sane length (like 80 characters) to keep it readable. In addition, we must do any formatting or indentation in the source file. Both BSD licenses contain a list of conditions that should be indented like a list, with blank lines in between. We could also potentially number the clauses; FreeBSD does in its copy, but the OSI versions do not. 2013-06-15 04:33:30 -04:00			`list of conditions and the following disclaimer.`
