A macro is a group of utilities.
Macros are useful when several modifications must be applied to repeatedly.
For example, if you need to batch convert files, offsetting their time and removing empty lines.
To create a macro, use the macros editor.
The macros also appear in the utilities tool, to be executed manually.
To assign an icon to the macro, create a PNG image with the same name as the XML file, or "Icon.png".
Use an image with minimum size 64×64 pixels, and 96 dpi.
