Managing .js file dependencies

[icogs]

I am fairly new to Javascript, coming from a Java & C/C++ background
so the possibility of a fundamental misunderstanding on my part cannot
be ruled out :-(

Lets say a friend sends me some really useful javascript code in
useful.js. I want to call some of this code in my own code in
myproject.js, making source in this file depenent on useful.js. Do I
need to have <script ..tags for both files or can I add something to
myproject.js which will manage this dependency for me?

You better have two `script' _elements_ for both _resources_.

or can I add something to myproject.js which will manage this
dependency for me?

There are dirty DOM hacks but as dirty hacks go they are unreliable.
