So, if I understand this correctly, you want to have this
do_install_append?

I was thinking the same. Changing the manifest generator might be
cleaner than "patching" the manifest file like this. However, it would
split the changes into three places: the recipe itself, the manifest
generator, and the generated manifest file. This would make it more
difficult for someone reading the recipe to understand how the
mechanism works. Anyway, please tell how you would like me to proceed
here: do you want to have the patch as it is done now or do you want to
see the generator changed?
