+#!/bin/bash
+# This script assumes that you have prepared various versions of
+# Minecraft bin folders in your $MC_HOME like this:
+# ${MC_HOME}/bin-version (example: ${MC_HOME}/bin-1.2.5)
+# 
+# The script tries to preserve the various versions of the bin folder
+# by copying the selected bin folder to a "working folder", to prevent
+# accidental updates on launch.
+#
+# Use at your own risk, changing minecraft versions around may result in
+# unexpected and undesirable behaviour. You may lose your saves.
+# This script does not handle backups of the world data, I suggest using
+# deja-dup or similar backup software. It's good for you.
