/**
 * While very nice, the default AWS EB CLI lacks one important feature: the ability to deploy the same code to
 * multiple environments. Of course, you can do that through multiple call to `eb deploy env1` / `eb deploy env2`, but
 * this is error prone.
 *
 * This can happen when you share the same code for a webserver and worker tier. This code is pretty simple and just
 * allows to bound one branch to multiple named environments.
