Definitelytyped: blueimp-md5: blueimp.md5 is not a function

• [x] I tried using the latest blueimp-md5.d.ts file in this repo and had problems.
• [x] I tried using the latest stable version of tsc. https://www.npmjs.com/package/typescript
• [x] I want to talk about xxxx/xxxx.d.ts.
  Error occurs when I try to use the definition file like this hashed = require("blueimg-md5").md5("my string").
  From npm page, we can see that the export of this module is simply a function.

    // Use the following version if you installed the package with npm: 
        var md5 = require("blueimp-md5"), 
        query = url.parse(req.url).query;
    // Calculate and print the MD5 hash of the url query: 
    res.end(md5(query));

The definition should be

declare module 'blueimp-md5' {
    function md5(value: string, key?: string, raw?: boolean): string;
    export = md5;
}

rather than

declare module 'blueimp-md5' {
    export function md5(value: string, key?: string, raw?: boolean): string;
}
