Angelo, All,

Thanks for the confirmation! :-)

My understanding, though, would be that we may need more than one such
versionned API. For example, I would (hypothetically!) develope my app
agaings current version, say 4.8-api, so I am using APIs from that
version. Then I update to a newer mono, and I start using the new APIs,
e.g. 5.3-api, in the new parts of my app, but the existing parts are
still using 4.8-api, so I need both.

Is that sensible, or did I mis-understood?

If correct, then we need to be able to select more than one versioned
API.

So, we an' rely on it being listed by the user; we must explicitly
install it.

    MONO_INSTALL_DIRS = \
        gac \
        $(fitler-out gac,$(call qstrip,$(BR2_PACKAGE_MONO_API_DIRS)))

    $(foreach dir,$(MONO_INSTALL_DIRS),copy the $(d) dir)

That would be awesome, thanks!
