From 270b30705dcca58d769a4ba8629cfb35eff32000 Mon Sep 17 00:00:00 2001 From: zimoun Date: Thu, 16 Sep 2021 13:47:33 +0200 Subject: packages: Factorize and document 'computed-origin-method'. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The 'computed-origin-method' had been introduced to work around limitations of the 'snippet' mechanism. The procedure was duplicated, which made it hard to automatically detect packages using it. * guix/packages.scm (computed-origin-method): Move procedure from... * gnu/packages/gnuzilla.scm: ...here and... * gnu/packages/gnuzilla.scm: ...there.
