 Templiér acts as a file watcher, proxy server and process manager.
 Once Templiér is started, it begins watching files in the `app.dir-src-root` directory.
 On start and on file change, it automatically builds your application server executable
-assuming that the main package is specified by the `app.dir-cmd` directory. Any custom
-Go compiler CLI arguments can be specified by `app.go-flags`. Once built,
-the application server executable is launched with `app.flags` CLI parameters and
-the working directory set to `app.dir-work`. When necessary, the application server
-process is shut down gracefully, rebuilt, linted and restarted.
