#summary Structure of the theme.cfg file

== Theme.cfg ==
This file gives the engine the values associated with a certain theme, to complement the graphics.
It is structured with a key followed by a number of values. Example:
<code>sky = 120, 40, 80</code>

There is also keys that replace existing keys under certain conditions, all keys preceding with "sd-" are used during sudden death and all keys with "rq-" are used when quality is reduced. These keys must be placed after the regular keys and they are all optional.

Following is the list of all current keys and their values, it is important to have the right number of values. Most keys may only be used once.

The values red, green, blue and opacity are in the range of one byte and can be specified in both decimal or hexadecimal form. The range are 0 - 255 or 0 - $FF.

Comments may be added by prefixing a semicolon(;) to the comment.
