 Description: swh-model
         =========
         
         Implementation of the Data model of the Software Heritage project, used to
         archive source code artifacts.
         
         This module defines the notion of Persistent Identifier (PID) and provides
         tools to compute them:
         
         ```sh
            $ swh-identify fork.c kmod.c sched/deadline.c
            swh:1:cnt:2e391c754ae730bd2d8520c2ab497c403220c6e3    fork.c
