Fixes #14016.

 - **event/alias**: All event attaching/triggering shorthands like `.click()` or `.mouseover()`.
 - **offset**: The `.offset()`, `.position()`, `.offsetParent()`, `.scrollLeft()`, and `.scrollTop()` methods.
 - **wrap**: The `.wrap()`, `.wrapAll()`, `.wrapInner()`, and `.unwrap()` methods.
-- **exports/amd**: Exclude the AMD definition.
-- **exports/global**: Exclude the attachment of global jQuery variables ($ and jQuery) to the window.
 - **core/ready**: Exclude the ready module if you place your scripts at the end of the body. Any ready callbacks bound with `jQuery()` will simply be called immediately. However, `jQuery(document).ready()` will not be a function and `.on("ready", ...)` or similar will not be triggered.
 - **deferred**: Exclude jQuery.Deferred. This also removes jQuery.Callbacks. *Note* that modules that depend on jQuery.Deferred(AJAX, effects, core/ready) will not be removed and will still expect jQuery.Deferred to be there. Include your own jQuery.Deferred implementation or exclude those modules as well (`grunt custom:-deferred,-ajax,-effects,-core/ready`).

+##### AMD name
+
+As an option, you can set the module name for jQuery's AMD definition. By default, it is set to "jquery", which plays nicely with plugins and third-party libraries, but there may be cases where you'd like to change this. Simply set the `"amd"` option:
+
+```bash
+grunt custom --amd="custom-name"
+```
+
+Or, to define anonymously, set the name to an empty string.
+
+```bash
+grunt custom --amd=""
