The XEGRM file format is a plain text document structure based on the TeX typesetting system and maintained by developers of the Grif structured document editor. It is primarily used for the composition of technical and scientific manuscripts that require precise control over mathematical symbols and typographic layout. As a static text-based format, it is inherently safe, though it is currently considered a legacy standard within the modern scientific publishing ecosystem.
