What's this?

load_plugins() public

Loads all plugins in config.plugin_paths. plugin_paths defaults to vendor/plugins but may also be set to a list of paths, such as

  config.plugin_paths = ['lib/plugins', 'vendor/plugins']

Each plugin discovered in plugin_paths is initialized:

add its lib directory, if present, to the beginning of the load path
evaluate init.rb if present

After all plugins are loaded, duplicates are removed from the load path. If an array of plugin names is specified in config.plugins, the plugins will be loaded in that order. Otherwise, plugins are loaded in alphabetical order.
