+ * Plugins
+ *
+ * Plugins are just node modules that contain a top level export "plugin" that implements
+ * the Plugin interface.
+ *
+ * 1. code-server uses $CS_PLUGIN to find plugins.
+ *
+ * e.g. CS_PLUGIN=/tmp/will:/tmp/teffen will cause code-server to load
+ * /tmp/will and /tmp/teffen as plugins.
+ *
+ * 2. code-server uses $CS_PLUGIN_PATH to find plugins. Each subdirectory in
+ * $CS_PLUGIN_PATH with a package.json where the engine is code-server is
+ * a valid plugin.
+ *
+ * e.g. CS_PLUGIN_PATH=/tmp/nhooyr:/tmp/ash will cause code-server to search
+ * /tmp/nhooyr and then /tmp/ash for plugins.
+ *
+ * CS_PLUGIN_PATH defaults to
+ * ~/.local/share/code-server/plugins:/usr/share/code-server/plugins
+ * if unset.
+ *
+ *
+ * 3. Built in plugins are loaded from __dirname/../plugins
+ *
+ * Plugins are required as soon as they are found and then initialized.
+ * See the Plugin interface for details.
+ *
+ * If two plugins are found with the exact same name, then code-server will
+ * use the first one and emit a warning.
+ *
+ */
+
+/**
+ * Programmability
+ *
+ * There is also a /api/applications endpoint to allow programmatic access to all
+ * available applications. It could be used to create a custom application dashboard
+ * for example. An important difference with the API is that all application paths
+ * will be absolute (i.e have the plugin path prepended) so that they may be used
