Not as extensive as I thought ;-)
unless I found only an early version,
but so here it goes:


* Download one release as git checkout:

git clone -b sources/v$version --single-branch \
  git://linux-libre.fsfla.org/releases.git linux-libre-$version/


* Example substitutions:

version=5.7-gnu upversion=5.7
prefix=linux-$upversion/


* If you plan on verifying any releases:

git archive --remote=git://linux-libre.fsfla.org/releases.git \
  --format tar master | tar -x -O keyring.gpg | gpg --import -


* If you plan on verifying release $version:

git archive --remote=git://linux-libre.fsfla.org/releases.git \
  --format tar logs/v$version | tar -x &&
if test -f linux-libre-$version.git.tar.sign; then
  prefix=linux-libre-$version/ targit=.git
else
  prefix=linux-$upversion/ targit=
fi


* Download/archive one release as git tarball:

# Use the conditional prefix above to be able to verify.
git archive --remote=git://linux-libre.fsfla.org/releases.git \
  --format tar.gz --prefix=$prefix sources/v$version \
  -o linux-libre-$version$targit.tar.gz


* Verify one release in git repo:

git archive --format tar --prefix=$prefix sources/v$version |
gpg --verify logs/v$version/linux-libre-$version$targit.tar.sign -


* Verify one release in a (gzip-compressed) tarball:

# Must have used the conditional prefix above to verify.
zcat linux-libre-$version$targit.tar.gz |
gpg --verify linux-libre-$version$targit.tar.sign -


* Download and verify a released compressed tarball:

ext=lz comp=lzip # ext=bz2 comp=bzip2 # ext=xz comp=xz
wget https://linux-libre.fsfla.org/pub/linux-libre/releases\
/$version/linux-libre-$version.tar.{$ext,sign} &&
$comp -d < linux-libre-$version.tar.$ext |
gpg --verify linux-libre-$version.tar.sign - # no $targit
