.SH "OPTIONS"

.IP "          \fB\-fs | \-\-fullscreen\fP         " 10
Enable fullscreen mode
.IP "          \fB\-glv | \-\-gl\-version\fP         " 10
Show the information of the current available OpenGL implementation on your machine then quit
.IP "          \fB\-dd | \-\-data\-dir newDataPath\fP         " 10
Specify to new path to OpenCity's data. For example: \-\-data\-dir /home/foo/bar/share/opencity/
.IP "          \fB\-cd | \-\-conf\-dir newConfigPath\fP         " 10
Specify to new path to OpenCity's configuration. For example: \-\-conf\-dir /home/foo/bar/etc/opencity/
.IP "          \fB\-na | \-\-no\-audio\fP         " 10
Disable the audio system 
.IP "          \fB\-\-generator\-height\-map heightMapPicture\fP         " 10
Load a gray\-level picture as height map (PNG). The water level is gray level 128, each map level is one gray level. That's why the whole picture seems to be in a medium gray, because there's only a minor difference between the pixels. You can draw yourself the height\-map or generate from any map sources. The interesting data for this work are the DEM satellite data. The map generator in OpenCity will crop the picture if it's too big.
.IP "          \fB\-\-generator\-seed seed\fP         " 10
The seed is the random integer seed used by the map generator
.IP "          \fB\-\-generator\-map MAP\-TYPE\fP         " 10
MAP\-TYPE: 0=plain (default), 1=hill, 2=mountain 
.IP "          \fB\-\-generator\-water WATER\-TYPE\fP         " 10
WATER\-TYPE: 0=dry, 1=lake (default), 2=coast 
.IP "          \fB\-\-generator\-map\-shape MAP\-SHAPE\-TYPE\fP         " 10
MAP\-SHAPE\-TYPE: 0=none (default), 1=island, 2=volcano, 3=crater 
.IP "          \fB\-\-generator\-tree\-density TREE\-DENSITY\-TYPE\fP         " 10
TREE\-DENSITY\-TYPE: 0=sparse (default), 1=normal, 2=dense
