A simple script is a text file with one command per line. See the [Internal Commands](usage.md#internal-commands) section, or type `/help` in the console to see the available commands. Any line beginning with `#` is ignored and treated as a comment.
Application variables defined with the `set` command or in the `[AppVars]` config section can be used. The following read-only variables are also available: `%username%`, `%login%`, `%serverip%`, `%serverport%`, `%datetime%`.
