XARGS is a specialized TeX macro definition format associated with the LaTeX document preparation system and maintained by contributors within the TeX community. This format is primarily utilized to define complex command structures and handle multiple optional arguments within automated typesetting workflows and document templates. Because the format consists of plain text macro instructions, it is inherently safe, though it is largely considered a legacy tool in modern LaTeX environments.
