The XWEB file format is a literate programming document structure developed for the XWEB system to integrate source code with descriptive documentation. It allows developers to maintain both computer code and its corresponding technical documentation within a single file, typically processed into TeX or programming language source files. As a legacy format primarily used in academic research environments, it carries a low security risk because it consists of plain text data requiring specialized software for execution.
