Version control of stars is fairly straight-forward, since one or multiple developers
can check-in/out the text files of the stars, but when you consider galaxies it
becomes stickier. For example, a developer may change a star that is called by many
galaxies, some that the developer is aware of and some he is not. This is analagous
to a developer changing a function that is called by many main programs. If the star
is dynamically linked into the galaxies, pre-existing galaxies may break. But if they
were statically linked, the result may be that pre-existing galaxies are giving
incorrect (or out-of-date) answers, unknown to the user or the developer. How is the
issue of version control addressed in the context of galaxies?
