-# Setup - creates the local repo which will be mirrored up to S3, then back-fill it. Your
-#         future deploys will eliminate all old versions without these backfill steps:
-#   aptly repo create signal-desktop
-#   aptly mirror create -ignore-signatures backfill-mirror https://updates.signal.org/desktop/apt xenial
-#   aptly mirror update -ignore-signatures backfill-mirror
-#   aptly repo import backfill-mirror signal-desktop signal-desktop signal-desktop-beta
-#   aptly repo show -with-packages signal-desktop
-#
-# First run on a machine - uncomment the first set of 'aptly publish snapshot' commands,
-#   comment the other two. Sets up the two publish channels, one local, one to S3.
-#
-# Testing - comment out the lines with s3:$ENDPOINT to publish only locally. To eliminate
-#          effects of testing, remove package from repo, then move back to old snapshot:
-#   aptly repo remove signal-desktop signal-desktop_1.0.35_amd64
-#   aptly publish switch -gpg-key=57F6FB06 xenial signal-desktop_v1.0.34
-#
-# Pruning package set - we generally want 2-3 versions of each stream available,
-#                       production and beta. You can remove old packages like this:
-#   aptly repo show -with-packages signal-desktop
-#   aptly repo remove signal-desktop signal-desktop_1.0.34_amd64

-#   NAME=signal-desktop(-beta) VERSION=X.X.X ./aptly.sh
