gulp-typings allows you to install typings from typings.json with gulp
var gulp = require("gulp");
var gulpTypings = require("gulp-typings");
gulp.task("installTypings",function(){
var stream = gulp.src("./typings.json")
.pipe(gulpTypings()); //will install all typingsfiles in pipeline.
return stream; // by returning stream gulp can listen to events from the stream and knows when it is finished.
});
