Subject: [PATCH] [new release] spawn (0.13.0)

CHANGES:

- Breaking change on Windows: to match the Unix behavior, `prog` is
  interpreted as relative to the directory specified by the `cwd`
  argument (janestreet/spawn#13)

- Switch to dune (janestreet/spawn#12)

- Switch to MIT+DCO (janestreet/spawn#11)

+synopsis: "Spawning sub-processes"
+description: """
+Spawn is a small library exposing only one functionality: spawning sub-process.
+
+It has three main goals:
+
+1. provide missing features of Unix.create_process such as providing a
+working directory
+
+2. provide better errors when a system call fails in the
+sub-process. For instance if a command is not found, you get a proper
+[Unix.Unix_error] exception
+
+3. improve performances by using vfork when available. It is often
+claimed that nowadays fork is as fast as vfork, however in practice
+fork takes time proportional to the process memory while vfork is
+constant time. In application using a lot of memory, vfork can be
+thousands of times faster than fork.
