From 61a71927194e7dd52df7e8c822612122b2e06b51 Mon Sep 17 00:00:00 2001 From: Antonin Godard Date: Tue, 11 Mar 2025 14:31:07 +0100 Subject: overview-manual/concepts: add UNPACKDIR in the directory description Mention that UNPACKDIR is used as a location to unpack the source code, and that S is the final location of the source code. This is deliberately vague, because as there are multiple instances of how these directories can be defined and used. The proper explanation of how the UNPACKDIR and S directories interact is left to the reference manual, under the UNPACKDIR variable description.
