## DESCRIPTION

Spring is a free Real Time Strategy (RTS) game engine, originally designed to play Total Annihilation (© 1997 Cavedog) content. It has since evolved into a general RTS engine, capable of running various kind of games (mods).

It is mainly designed around online multiplayer games but can also be played in single-player mode against AIs.

This is the dedicated, GUI-less server for hosting multiplayer games. You need to feed it a start script in order to have it host a game. Start script are generated by lobby clients (SpringLobby) or autho-hosts (Spads, Springie). This is the most leight-weight version of the engine, which basically only redirects network traffic, while spring-headless still runs a full blown simulation of the game.

## OPTIONS

- **-h, --help**

  Print the options help message and exit

- **-V, --version**

  Display program version and exit

- **--sync-version**

  Display program sync version (for online gaming) and exit

- **-i, --isolation**

  Limit the data-dir (games & maps) scanner to one directory (see --isolation-dir and the SPRING\_ISOLATED env var)

**--isolation-dir**::'PATH'

Specify the isolation-mode data-dir (see --isolation and the SPRING\_ISOLATED env var)

## DATA DIR

Data directories are searched for content, and among other things, may contain: \*cache \*games \*maps \*AI

When running the engine, it may use multiple data directories, but it will use only a single one of them as writable, to write cache & log files to.

## FILES

```
~/.spring/
```

The default data-directory (see section DATA DIR).

```
~/.springrc
```

Contains the users settings for the engine, for things like graphic and sound.

```
/etc/spring/datadir
```

Contains the *:* separated paths to additional data-dirs (see section DATA DIR).

## ENVIROMENT VARIABLES

**SPRING\_LOG\_SECTIONS** Selective functionality to change the verbosity (separated by *,*).

**SPRING\_DATADIR** Adds additional directories Spring will search for files (separated by *:*).

**SPRING\_ISOLATED** If defined, Spring will stop searching files outside of the binaries directory. If it is set to a valid directory path, it will be used as the isolation directory. See the --isolation and the --isolation-dir options.
