I am evaluating bndtools as an alternative to the websphere OSGi tooling in eclipse, to package liberty profile features.
Liberty profile uses OSGi subsystems packed as a .esa for extensions to the runtime. It appears that it is possible to package a subsystem using BND, based on this file in the bnd git repo.
But I can't find any documentation about how to setup an ESA project. Can someone give me some pointers?
