Making modifications available

Hi,

I've been working on a commercial application that embeds Mozilla. I
think I've satisfied the terms of the MPL, as I have kept all Moz code
where it is, and have just my own code inside my application.

However, in order to make Gecko work exactly like I wanted, I needed to
make a couple of (small, but rather ugly) modifications to the source
files from which I built it. Obviously I need to make these changes
available.

Is it sufficient to add a link in the docs/application to patches that
contain the new code, plus links to where the original code may be
downloaded from mozilla.org? Or do I have to make the whole patched
source tree available on my website?

Thanks,
Simon
