+//! This module contains the code of extension installation.
+//!
+//!
+//! # How
+//!
+//! Technically, installing an extension involves the following steps. The order
+//! may vary between implementations.
+//!
+//!   1. Check if it is already installed, if so, return
+//!   
+//!   2. Correct the `plugin.json` JSON if it does not conform to our `struct
+//!      Extension` definition. This can happen because the JSON written by
+//!      developers is in a simplified form for a better developer experience.
+//!
+//!   3. Validate the corrected `plugin.json`
+//!      1. misc checks
+//!      2. Platform compatibility check
+//!
+//!   4. Write the extension files to the corresponding location
+//!
+//!      * developer directory
+//!        * extension directory
+//!          * assets directory
+//!            * various assets files, e.g., "icon.png"
+//!          * plugin.json file
+//!          * View pages if exist
+//!
+//!   5. If this extension contains any View extensions, call `convert_page()`
+//!      on them to make them loadable by Tauri/webview.
+//!
+//!      See `convert_page()` for more info.
+//!
+//!   6. Canonicalize `Extension.icon` and `Extension.page` fields if they are
+//!      relative paths
+//!
+//!      * icon: relative to the `assets` directory
+//!      * page: relative to the extension root directory
+//!
+//!   7. Add the extension to the in-memory extension list.
