+#!/bin/bash

+# This copies 2 files, cards.txt and cards_desfire.txt from brmdoor@brmlab.cz
+# Shows the mtime (modified time according to server), which should be set to:
+#
+# $ cat /etc/timezone 
+# Europe/Prague
+#
+# Use same timezones, you'll have less headache
+# The mtime check is just a sanity check, a human should check if it's correct
+#
+# ANY TIME YOU CAN ABORT THE SCRIPT WITH CTRL-C, BUT DABASE CHANGES THAT HAPPENED
+# WILL NOT ROLL BACK!
+#
+# Then it will show diff of cards existing and to be imported in vimdiff
+# Overview and use !q to exit
+#
+# Script will ask 3 times, Enter is accept, Ctrl-C is abort:
+# 1) do you agree with the mtimes, are they corre
