<body><div>It is done by the applications list in the .app files. It isn't possible to check that C will never be used in your example. xref can probably used to find some cases. But it is up to the user to add to the relx config `{exclude_apps, [C]}` which tells relx to not only not include C but also remove C from any .app file that had it listed.<br></div>

<div>How does it make a decisions what is needed? As far I re-call, it is made at high level only. If you app uses application A that use B and C then all apps are included into release and their code is loaded into memory even if feature of A that uses C is not ever called from my application, right? or it appliance heuristic and pick only the modules that definitely used by the application (in this case C will not be ever included into release)? <br></div>
