+
+# DESCRIPTION
+# An attempt to seese industrial... ops, I ment an attempt to make my
+# bash prompt nicer and save all my bash history ordered by date with
+# exit codes for later review...

+
+# KNOWN BUGS:
+# - logs the previous command again on control-break, control-quit
+# - logs the last command in history on control+d (EOF) or enter
+#   (could be fixed if we remember the index of the command used last time,
+#   which is currently removed by 'Cmd=${Cmd:7}')
+# - does not log history from within mc (midnight commander)
+#   this can be viewed as a feature too :-) The problem is that mc
+#   changes PROMPT_COMMAND, hurting the prompt quite bad and
+#   killing the log.
