  # Select a profile that is used for building the binary. The profile optimizes for certain use-cases.
  # For distribution builds we want to reduce the size of the binary as much as possible. Whereas in
  # regular CI builds we just want the fastest build possible.
  #
  # We switch based on the branch that is being built. If it's the main branch or a tag, we use the `dist`.
