Blob Blame History Raw
From 1dc9372821487ccace23ff1ae9cba6b30f02c91c Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add SourceLicense tag to spec syntax

to set a separate license to the source RPM. This can be useful if the
sources have code under additional licenses that do not end up in the
binary packeges.

Resolves: #2079

Note on the backport:  The spec document on this branch is ancient and
doesn't even contain the License tag's description so this backport
leaves the documentation part out.

(backported from commit 9ed9d3fce34bc3c8121989e0cf263528e7e68756)
