## Running the compiler using nailgun
This gets around the long startup time of Google Closure Compiler using Nailgun, which runs a single java process in the background and keeps all of the classes loaded.

First you need to install closure-gun by running the following command.
```bash
npm install closure-gun
```

### Gulp
```js
var compilerPackage = require('google-closure-compiler');
var closureCompiler = compilerPackage.gulp();

compilerPackage.compiler.JAR_PATH = undefined;
compilerPackage.compiler.prototype.javaPath = './node_modules/.bin/closure-gun'
```

Note that when using gulp, Only without gulp.src works with nailgun.

### Grunt
```js
var compilerPackage = require('google-closure-compiler');
var closureCompiler = compilerPackage.grunt();

compilerPackage.compiler.JAR_PATH = undefined;
compilerPackage.compiler.prototype.javaPath = './node_modules/.bin/closure-gun'
```

## Specifying Extra Java Arguments
Some users may wish to pass the java vm extra arguments - such as to specify the amount of memory the compiler should
be allocated. Both the grunt and gulp plugins support this.
