Patch Multiple Files from Multiple Directories

  The Patch Plugin can be configured to apply sets of patches from multiple directories.
  In the example below, the plugin is setup to apply all the patches in a <<<bugfix>>> directory with 
  optimization (will not reapply the same patch) and also from an <<<enhancement>>> directory.  This 
  scenario might crop up if you don't have commit access to a project's source yet need to apply 
  bugfix and enhancement patches.  The two different patch source directories are shown purely as 
  an example of what can be configured.
