From fe40a1722481c2f04c742445e7a8fb2eee7a481d Mon Sep 17 00:00:00 2001 From: "Ryan C. Gordon" Date: Thu, 18 Dec 2014 00:19:52 -0500 Subject: [PATCH] Initial merge of Emscripten port! With this commit, you can compile SDL2 with Emscripten ( http://emscripten.org/ ), and make your SDL-based C/C++ program into a web app. This port was due to the efforts of several people, including: Charlie Birks, Sathyanarayanan Gunasekaran, Jukka Jyl?nki, Alon Zakai, Edward Rudd, Bruce Mitchener, and Martin Gerhardy.
