It's a soyutils.js from Google Closure Templates library, packaged as a RequireJS module.
I'm not adding, not removing anything from original soyutils.js (see soyutils.origin.js), just a repackaged
version of the library.
I've split original library into smaller RequireJS modules (src dir), and made an optimized version as
soyutils.min.js. You can make your own version by executing build.sh
Based on build from 21 Dec 2012 (closure-templates-for-javascript-latest.zip, SHA1 checksum
6c264845a48d1ba59d8c725c593530be003cf525)
You can download original version from https://code.google.com/p/closure-templates/
Same as original library.
