+[Per-Directory-History][6]
+=========================
+
+Per directory history for zsh, as well as global history, and the
+ability to toggle between them with ^G.
+
+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.
+
+This is a standalone repository for the script, however it is also included in
+[oh-my-zsh][4] as a plugin.
+
+----------------------------------------------------------------------------
+Usage
+----------------------------------------------------------------------------
+
+1.  Load this script into your interactive ZSH session:
+
+        % source zsh-per-directory-history.zsh
+
+2.  The default mode if per directory history, interact with your history as normal.
+
+3.  Press ^G (the Control and G keys simultaneously) to toggle between local
+    and global histories. 
+
+
+
+-------------------------------------------------------------------------------
+Configuration
+-------------------------------------------------------------------------------
+
+* HISTORY_BASE a global variable that defines the base directory in which the 
+  directory histories are stored
+* per-directory-history-toggle-history is the function to toggle the history
+
+-------------------------------------------------------------------------------
+History
+-------------------------------------------------------------------------------
+
+The idea/inspiration for a per directory history is from [Stewart MacArthur][1] 
+and [Dieter][2], the implementation idea is from [Bart Schaefer][3].  The 
+implementation is by [Jim Hester][5] in September 2012.
