Let’s say that I installed package A that depends on package B. After a while, package A no longer depends on package B. All the other packages also do not depend on package B. Will package B be uninstalled automatically if I run gc in the package manager?

The package will be removed from your manifest already when you `Pkg.rm` the last package requesting `B`. `Pkg.gc` will eventually remove also the directory of the package itself if it isn’t present in any active manifest
