[Javascript] Including additional javascript files

[Alex Robinson]

Some time ago I stumbled across a technique for including additional 
external javascript files that mirrored the way that additional CSS 
files can be included via the @import statement.

Of course, I can't even begin to remember when or, more crucially, 
where I did the stumbling, and my attempts to google it out of thin 
air are being met with countless handy tips on how to replicate 
SSI/PHP includes with document.write.

Anyone have any ideas as to where I might find this technique again?
