commit 7d8b59139a5adeaed3f72b4e5e4749a13a77300b
Author: Christopher Baines <[email protected]>
Date: Sun Jan 15 09:00:59 2017 +0000
services: Export 'service-extension' procedures.
* gnu/services.scm: Export service-extension-target and
service-extension-compute. This allows for greater extensiblity of services
by enabling service extensions to be wrapped. For example, the parameters
passed to the compute function can be modified, or the return value of the
compute function can be modified.
