%TOOLBOX_PATH_CACHE   MATLAB Toolbox Path Cache
%
%   In order to reduce the time required to launch MATLAB,  V6 provides
%   a new feature for caching toolbox directory information across sessions.
%   This technique can offer a dramatic reduction in startup time,
%   particularly when launching MATLAB from a network server.  To utilize
%   this feature, you will need to generate a toolbox path cache file,
%   which contains a snapshot of your current toolbox directory hierarchy.
%   To do so:
%   
%           * Start MATLAB
%           * Open the Preferences Dialog under the File menu
%           * Check the "Enable toolbox cache" item
%           * Click the "Update Toolbox Cache" button
%   
%   You will need to have write permission in $MATLAB/toolbox/local in
%   order for this command to complete successfully. The next time you
%   start MATLAB, you should see a message of the form:
%   
%        MATLAB Toolbox Path being initialized using Toolbox Path Cache.
%   
%   and an accompanying reduction in startup time.
%   
%   If you are running on a platform without the IDE Desktop, you
%   can accomplish the same result by issuing the command:
%   
%        >> rehash toolboxcache
%   
%   at the MATLAB prompt.
%   
%   As with any caching technique, there are a few caveats to be aware of
%   when using this feature.  If you install a new toolbox or update from
%   The MathWorks, the installer will mark the cache as invalid and MATLAB
%   will cease using it, instead issuing a message at startup of the form:
%   
%        MATLAB Toolbox Path Cache is out of date and is not being used.
%   
%   This message means that you need to refresh your toolbox path cache file
%   through the IDE preferences or the REHASH command as described above.
%   
%   If you make your own changes to toolbox directories (e.g. add or delete
%   files under $MATLAB/toolbox,) you will need to update the cache in this
%   same manner, but MATLAB will not provide any indication that this is
%   necessary other than that it will not find your new files.
%   
%        NOTE: FOR THIS REASON, WE STRONGLY RECOMMEND THAT YOU NOT DO
%              DEVELOPMENT WORK IN THE TOOLBOX AREA WHEN USING PATH CACHING.
%   
%   You can disable usage of this feature either on a user-by-user basis or
%   on a global basis.  To disable it on a per-user basis, go to the
%   preferences dialog and un-check the  "Enable toolbox cache" item.  To
%   disable it on a global basis, remove the file:
%   
%        $MATLAB/toolbox/local/toolbox_cache.mat
