And we at Mozilla (and, I'm sure, Mono and others) would like to thank
_you_ profusely for your co-operation and willingness to undertake
this non-trivial amount of work in order to help us (and others) use
Cairo in our software.  You certainly did your bit in making the
conversations pleasant!

Further, for what it's worth, the Mozilla project will for its part
sternly advise against any such MPL-only fork, much as Richard
Stallman and Miguel de Icaza advised against GPL-only forking of the
Mozilla codebase when we made our code available under the
MPL/LGPL/GPL triple-license.

It is certainly in Mozilla's best interest to keep the larger
community of Cairo developers, of which we are now quite pleased to be
a part, focused on improving a single codebase.

Thanks again,
