/**
* Overlay
*
* The homepage of code-server will launch into VS Code. However, there will be an overlay
* button that when clicked, will show all available applications with their names,

* to <code-server-root>/<plugin-path>/<app-path> to access the application.

/**
* 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
* directly.
*
* Example output:
*
* [
