License for Glyphicons is unclear

Created by: justinshepard

The license terms for Glyphicons when used with Bootstrap needs to be clarified. For example, including a link to Glyphicons on every page in a prominent location isn't possible or appropriate for some projects. Purchasing the set for each project is certainly not out of the question, however I would like to see the license terms explicitly stated prior to having to add a line item for icon purchase to invoices.

According to the Glyphicons license page , Halflings isn't included in the Glyphicons FREE set but it's suggested on the Bootstrap site that a special agreement has been made between Twitter and Glyphicons to include Halflings with Bootstrap:

Glyphicons has granted us use of the Halflings set in our open-source toolkit so long as we provide a link and credit here in the docs. Please consider doing the same in your projects.

I am not a lawyer, but the phrase "has granted us use of the Halflings set" suggests to me (and my colleagues) that only the Bootstrap project has been granted a special license and that users of the toolkit would be subject to Glyphicons' normal license. Someone recently proposed a question of the Halflings set's license to Glyphicons on Twitter and the response was ambiguous but seemed to suggest that any attribution was acceptable when using Glyphicons with the Bootstrap toolkit:

If it's not possible to include a link back to glyphicons.com, it would be right to have any license, but it's up to you.

Please update the Bootstrap website and/or the LICENSE file distributed with the source to expicitly state the license terms for the Glyphicons Halflings set when used with Bootstrap, whatever those terms may be. This will help those of us striving for compliance to determine whether to use Glyphicons or an alternative icon set with less intrusive license terms (such as FontAwesome).
