This directory is used for my development purposes.

Here I can patch eclipse source files and update the corresponding plugin jar
in eclipse.

Steps:
  1) create directory with the plugin name, without the plugin version, and any
     necessary package directories.
     Ex. $ mkdir -p patch/org.eclipse.ui.workbench/org/eclipse/ui/internal
  2) add any src files to be patched.
  3) Run the patch ant task.
     $ ant patch
  4) To revert all patches based on available plugin dirs:
     $ ant patch.revert

Note: for jars included in a plugin directory the patch path can include the
path to the nested jar and that jar will be updated (jars nested in a plugin jar
are not yet supported):

  Ex. patch/org.apache.ant/lib/ant.jar
