The HANDLERS format is a text-based artifact generated by or associated with the TeX typesetting system developed by Donald Knuth. These files typically function as execution transcripts or configuration scripts that define input processing rules within specific TeX directory structures. While generally considered a legacy component in modern typesetting workflows, the format remains a plain text container with no inherent execution capabilities or security vulnerabilities.
