	Well, perhaps would be better to patch pretty ;-).

	The weights given by ClustalW are the weights used for
the weighted profile calculation during the multiple alignment
process. We feel useful for the user to know what were the weights

	Also, it's just a patch on an output format option, I
would like to see a printf("weight scaled for pretty compatibility\n").
with a scale factor indicated here...

	And yes, the new licence of GCG does not permit very
easily fixes on GCG programs, but is it a good reason to submitt
a patch on our program? Nothing was possible on the GCG side?

	Anyway, we will apply your changes to the following version
of Clustal, and document it a little bit.
