please leave this notice in tact.

should you improve upon this code, please
let me know so that I may update the version
hosted on slayeroffice

--- to use --
reference this file (on your own server) as a javascript src
in the head of your document. give the elements
you want a gradient background applied to a class as such:

class="gradient 000000 ffffff horizontal" or
class="gradient 000000 ffffff vertical"

See http://slayeroffice.com/code/gradient/ for more examples.
