‡  ZS )ÚAbstractDistributiona¦  A base class for handling installable artifacts.

    The requirements for anything installable are as follows:

     - we must be able to determine the requirement name
       (or we can't correctly handle the non-upgrade case).

     - for packages with setup requirements, we must also be able
       to determine their requirements without installing additional
       packages (for the same reason as run-time dependencies)

     - we must be able to create a Distribution object exposing the
       above metadata.

     - if we need to do work in the build tracker, we must be able to generate a unique
       string to identify the requirement in the build tracker.
