-Why Two Licenses?
-=================

-The zlib License could have been used instead of the Modified (3-clause) BSD

-libjpeg-turbo binary distributions under the IJG License.  However, the IJG
-License specifically refers to the Independent JPEG Group and does not extend
-attribution and endorsement protections to other entities.  Thus, it was
-desirable to choose a license that granted us the same protections for new code
-that were granted to the IJG for code derived from their software.
