* 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,
* icons and provider plugins. When one clicks on an app's icon, they will be directed
* to <code-server-root>/<plugin-name>/<app-name> to access the application.

/**
* Plugins
*
* Plugins are just node modules.
*
* 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.
*
* code-server also 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.
*
* Built in plugins are also loaded from __dirname/../plugins
*
* Priority is $CS_PLUGIN, $CS_PLUGIN_PATH and then the builtin plugins.
* After the search is complete, plugins will be required in first found order and
* initialized. See the Plugin interface for details.
*
* 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.
