-#!/usr/bin/env zsh
-#
-# This is a implementation of per directory history for zsh, some
-# implementations of which exist in bash[1,2]. It also implements
-# a per-directory-history-toggle-history function to change from using the
-# directory history to using the global history. In both cases the history is
-# always saved to both the global history and the directory history, so the
-# toggle state will not effect the saved histories. Being able to switch
-# between global and directory histories on the fly is a novel feature as far
-# as I am aware.
-#
-#-------------------------------------------------------------------------------
-# Configuration
-#-------------------------------------------------------------------------------
-#
-# HISTORY_BASE a global variable that defines the base directory in which the
-# directory histories are stored
-#
-#-------------------------------------------------------------------------------
-# History
-#-------------------------------------------------------------------------------
-#
-# The idea/inspiration for a per directory history is from Stewart MacArthur[1]
-# and Dieter[2], the implementation idea is from Bart Schaefer on the the zsh
-# mailing list[3]. The implementation is by Jim Hester in September 2012.
