-### Pack resource files
-
-Rustdesk can pack resource files in one exe file.
-Then extract files to the installation directory when being installed.
-
-This design makes rustdesk run both simple mode(single exe file) and full mode(all files after been installed).
-
-To pack resource files, follow the steps:
-1. cd rustdesk
-2. mkdir `resources` directory
-3. put files to `resources`
-4. cargo build --features with_rc,<other features>
-
-Feature `with_rc` is introduced to pack and extract resource files.
-
-#### Lib `simple_rc`
-
-A lib named `simple_rc` is used to pack and extract resource files.
-
-##### Generate resource packed file
-The pack process workflow:
-1. Parse the specified directory tree.
-2. Exclude specified files.
-3. Read all file contents, save as byte arrays in source file(`rc.rs`), and remember file names.
-
-`simple_rc` accepts either a configuration file or a `Config` structure.
-
-1. Generate resource packed with configuration file.
-```
-fn generate(conf_file: &str) -> ResultType<()>
-```
-```
-# The output source file
-outfile = "src/rc.rs"
-
-# The resource config list.
-[[confs]]
-# The file or director to integrate.
-inc = "D:/projects/windows/RustDeskTempTopMostWindow/x64/Release/xxx"
-# The exclusions.
-exc = ["*.dll", "*.exe"]
-# The front path that will ignore for extracting.
-# ${OutputPath} = ${InstallDir} + (${inc} - ${suppressed_front})
-# The following config will make base output path to be "RustDeskTempTopMostWindow/x64/Release/xxx".
-suppressed_front = "D:/projects/windows"
-```
-
-2. Generate resource packed file with a `Config` structure:
-```
-fn generate_with_conf<'a>(conf: &'a Config) -> ResultType<()>
-
-...
-    generate_with_conf(&Config {
-        outfile: "src/rc.rs".to_owned(),
-        confs: vec![ConfigItem {
-            inc: "resources".to_owned(),
-            exc: vec![],
-            suppressed_front: "resources".to_owned(),
-        }],
-    })
-    .unwrap();
-...
-```
-
-##### Extract files
-
-Extraction will keep the resource direcotry tree.
-
-The extraction process workflow:
-1. Create directory if needed, to restore the directory tree.
-2. Write contents to the associated file names.
-
-```
-fn extract_resources(root_path: &str) -> ResultType<()>
-```
-
-##### Note
-
-File attributes like privileges, create time, owner, are not supported.
