-# A plugin can be 'site', 'jvm', or both.

-### example site plugin for "foo":
-#
-# foo.zip <-- zip file for the plugin, with this structure:
-#   _site/ <-- the contents that will be served
-#   plugin-descriptor.properties <-- example contents below:

-# site=true

-### example jvm plugin for "foo"

-#   <arbitrary nameN>.jar <-- any number of jars
