		## Manual package resolution

		Code like this will not work, because an AST parser is not smart enough to evaluate variables into strings.

		```js
		var moduleName = 'myModName';
		var computed = require(moduleName);
		```

		It can be rewritten like this, using the `resolve` function:

		```js
		var resolve = require('jest-webpack-alias').resolve;
		var moduleName = 'myModName';
		var computed = require(resolve(moduleName, __filename));
		```
