the forge shell script itself should be able to kick off an installation of an addon
forge --install org.example:plugin,2.0.0-SNAPSHOT —repository=~/.forge/custom_addons_dir
so would that start forge, install an addon, and forge be ready with that addon?
it would then shut down
but the addon would be installed
so basically like forge -e
but just for installing addons
removal should also be possible
and listing what's there
should be easy to do!
