Developing plugins in an IDE is convenient, especially for debugging. To

that end, the plugin contains a _main()_ method which sets the _plugins.dir_

system property (so that the plugin is added to the Plugins menu), starts

ImageJ, loads an image and runs the plugin.



Since this project is intended as a starting point for your own

developments, it is in the public domain.
