-// Type definitions for assert and power-assert
-// Project: https://github.com/Jxck/assert, https://github.com/twada/power-assert
-// Definitions by: vvakame <https://github.com/vvakame>
-// Definitions: https://github.com/DefinitelyTyped/DefinitelyTyped
-
-// Definitions for commonjs-assert match that of node.js' assert module,
-// but commonjs-assert is intended to be used as an independent module,
-// for instance when making a stand-alone site or app that doesn't have
-// access to node modules. For that reason, these definitions define a
-// "assert" module. This will conflict with node.d.ts and other assert
-// modules such as "power-assert", but a project should realistically
-// only be using one of these at a time.
