+# VCS Backup is a configuration for setting up a version control system mirrors.
+# Currently Mercurial (Hg) and Git are supported.
+# Features:
+#  - mirrors remote repositories
+#  - creates Btrfs subvolume for each repository
+#  - does periodic pull to keep mirrors up to date
+#  - does periodic Btrfs snapshot to keep history (git push --force done on the remote repository will lead to modifications or deletions in our current mirror, but previous versions will be kept in the snapshots)
+#  - provides web interface for remote clonning of our mirrors (see systemd and etc folders)
+#  - can be controlled over SSH by a sane person / owner of the system
+#  - provides reports in the recfile format (to be processed using GNU Recutils or Relational pipes):
+#     - list of repositories/mirrors
+#     - results of pull operations
+
+
+# This is an asynchronous message-driven shell script that runs distributed across two machines and four user accounts. You have been warned :-)
