### 4.1 Basic options

#### 4.1.1 about

Command-line option: `--about=<value>`

  Type: string

  Will allow you to get informations about a given keyword. Let’s say that, for instance, you want informations about the keyword ’map-path’. Simply run ’liquidwar6 –about=map-path’. Note that this internal self-documentation system can describe command line switches as well as XML config file parameters or environment variables, and even some Guile script functions. The ’–list’ command line switch will give you the list of all available keywords.

#### 4.1.2 audit

Command-line option: `--audit`

  Display all path values, defaults and current settings. This output is very usefull to track down problems such as missing directories, broken installations. If you get an error message that suggests some file is missing, then give this option a try.

#### 4.1.3 copyright

Command-line option: `--copyright`

  Returns the copyright notice for the program.

#### 4.1.4 credits

Command-line option: `--credits`

  Gives hopefully extensive information on who contributed to the game.

#### 4.1.5 debug

Command-line option: `--debug`

  Enables debug mode. This will turn on maximum log information, and display everything on stderr, even messages which are normally only stored in the log file.

#### 4.1.6 defaults

Command-line option: `--defaults`

  Clears the config file and run the game with default settings. Use this if you suspect you have broken something by tweaking user settings, or when upgrading the game to a new version.

#### 4.1.7 help

Command-line option: `--help`

  Returns a short help for the program.

#### 4.1.8 host

Command-line option: `--host`

  Display all known system host properties, including os and cpu informations.

#### 4.1.9 list

Command-line option: `--list`

  Returns the list of all keywords which can be queried for information. This includes command-line options, environment variables, and so on. This is the companion option of ’–about’. Results obtained with ’–list’ can be passed to ’–about’.

#### 4.1.10 modules

Command-line option: `--modules`

  Tells which modules have been enabled when the game was compiled. It’s still possible to add or remove modules afterwards, but this option allows you to know how things were at first.

#### 4.1.11 pedigree

Command-line option: `--pedigree`

  Display all build values, these are general constants which can help debugging, tracing what binary you are running, and so on. It’s a good idea to take a look at the output of ’pedigree’ if you have problems running the game.

#### 4.1.12 test

Command-line option: `--test`

  Runs a (hopefully) complete test suite which will call most internal Liquid War 6 functions and check out wether they work, in a simple context, without any game interference. Usefull for troubleshooting.

#### 4.1.13 version

Command-line option: `--version`

  Returns the version of the program, as defined by the GNU Coding Standards.
