-// Config for testing all available plugins
-// 
-// To run it do these steps:
-//
-// 1. Clone these repositories:
-// ```
-// git clone https://github.com/eclipse-zenoh/zenoh.git
-// git clone https://github.com/eclipse-zenoh/zenoh-backend-influxdb.git
-// git clone https://github.com/eclipse-zenoh/zenoh-backend-rocksdb.git
-// git clone https://github.com/eclipse-zenoh/zenoh-backend-filesystem.git
-// git clone https://github.com/eclipse-zenoh/zenoh-plugin-webserver.git
-// git clone https://github.com/eclipse-zenoh/zenoh-plugin-mqtt.git
-// git clone https://github.com/eclipse-zenoh/zenoh-plugin-dds.git
-// git clone https://github.com/eclipse-zenoh/zenoh-plugin-ros1.git
-// git clone https://github.com/eclipse-zenoh/zenoh-plugin-ros2dds.git
-// ```
-//
-// 1.1. Init submodules for zenoh-plugin-ros1
-// ```
-// cd zenoh-plugin-ros1
-// git submodule init
-// git submodule update
-// ```
-//
-// 2. Build projects
-// ```
-// cd zenoh && cargo build && cd ..
-// cd zenoh-backend-influxdb && cargo build && cd ..
-// ...
-// ```
-//
-// 3. Run the zenohd server with this config file.
-//
-// Explicit setting RUST_LOG=info is important: without it the logs are printed by zenohd itsellf, but not by plugins.
-// ```
-// cd zenoh
-// RUST_LOG=info cargo run -- --config plugin_test_config.json5
-// ```
-// 
-// Some errors on plugin initalisation are expected due to some mandtatory properties missing in the config file, like for "influxdb" and "influxdb2" volumes.
-// Though there supposedly should not be plugin loading errors due to not found files or version incompatibility
-//
-//
-// 4. Test access plugin status through admin space
-//
-// The plugins information is available by "@/router/{router_id}/plugins/**". Each plugin provides by this key the json object with its status.
-// Subplugins are also available by this key, e.g. "@/router/{router_id}/plugins/storage_manager/influxdb".
-// ```
-// cargo run --example z_get -- -s "@/router/*/plugins/**"
-// ```
-// result is
-// ```

-// ...
-// ```
-//
