General format description

The Swayimg configuration file is a text-based INI file used to override the default settings.

The structure of the INI file consists of key-value pairs for properties and sections that organize properties. The basic element contained in the INI file is the key or property. Every key has a name and a value, delimited by an equals sign (=). The name appears to the left of the equals sign. The value can contain any characters.

Keys are grouped into named sections. The section name appears on a line by itself, in square brackets ([ and ]). All keys after the section declaration are associated with that section.

The number sign (#) at the beginning of the line indicates a comment. Empty lines and comments are ignored.
