+#!/usr/bin/env bash

+# Manages aptly input repositories and publishes a merged output repository.
+# Structure is as follows:
+# repo1 ───> snapshot "repo1-%Y-%m-%d" ─┬─> snapshot "%Y-%m-%d" ───> publish inside $TBASE/public
+#                                       │
+# repo2 ───> snapshot "repo2-%Y-%m-%d" ─┘
+# 
+# Furthermore, our PACKAGE input folder is /tmp/aptly with repository names as subfolder, so if
+# you want a new package added inside repo1, you would place a file inside /tmp/aptly/repo1/.
+# The package would then be added and its file inside /tmp be removed.
+#
+# Why bash?
+# 1. This script is INTERACTIVE, it asks for your GPG passphrase before signing packages
+# 2. It still uses a lot of syscalls like aptly
+# 3. The steps we do are still not that resource-hungry, so the downsides while using bash are rather low
+# The combination of these three led to bash in the first iteration.
+#
+# What doesn't this script do?
+# 1. It does not create the source repos or the aptly config.
+# 2. It does not repair if one of the parts of the structure above is missing; in that case,
+#    we assume an extraordinary failure and will fail ourselves. Exception: We skip failing
+#    on removal if a published repo or a snapshot does not exist.
+# 3. It does not manage multiple snapshots yet. Nor does it cleanup snapshot remainders in case the script
+#    is interrupted. Both can be considered a TODO.
