Installing 3rd party plugins
Please try to avoid closed-source plugins.
Just move the .jar into staged-plugins/, and create/adjust the corresponding .config file (also in staged-plugins/). Then type "make" and it will be added/updated and committed.
The .config file should look something like this:
File, "Show Prime Numbers", Primes_("")
where "File" is the menu you want to add the item to -- at the moment, the only valid choices are "Plugins", "Plugins><submenu>", "File>Import", "File>Save", "Analyze>Tools", "Help>About" and "Edit>Options".
Next comes the title of the menu item, and lastly the class name of the plugin with a parameter that will be passed to the run() method of that class.
In other words, the .config file will become the plugins.config of the .jar file.
Please make sure that your .config file is designed such that the menus fit in snuggly with the common Fiji menu structure.
Then just "make", and the plugin will be automatically installed and committed (this needs "git" installed, though).
