The ROLES format is a plain text configuration structure developed by Donald Knuth for managing user permissions and macro roles within legacy TeX typesetting environments. It is primarily utilized to define document processing rights, font accessibility parameters, and administrative roles across shared typesetting servers and archival systems. As a legacy format, it has largely been superseded by modern TeX distribution management tools, but remains safe for use as it contains no executable code or dynamic scripting capabilities.
