Gtatool is a command line tool to manipulate GTAs.

It provides a set of commands that manipulate GTAs on various levels: array element components, array dimensions, whole arrays, and streams of arrays. For example, you can add components to array elements, merge separate arrays into combined arrays in different ways, apply global transformations to array data, reorder the array data, and much more.

Additionally, gtatool can import from and export to many other file formats, including:

Use gta help to get a list of all available commands, and gta help <cmd> to get help for the command <cmd>.

The gui command provides a graphical user interface for a subset of the full functionality.
