Convert LATEX to OPML

LaTeX, short for "Lamport TeX", is a typesetting system widely used for producing scientific and mathematical documents due to its powerful handling of formulas and bibliographies. LaTeX files contain plain text formatted with LaTeX markup language, which then gets processed to produce high-quality PDFs. Originating from Donald Knuth's TeX system in the late 1970s, LaTeX was further developed by Leslie Lamport in the 1980s to simplify document preparation. It remains essential in academia and research for creating complex documents with precision and clarity.

OPML, or Outline Processor Markup Language, is a file format utilized primarily for outlining data structures. Initially developed in 2000 by UserLand Software, OPML was designed to facilitate the exchange of outline-based information between different software applications. Its uses have expanded over time, notably in organizing RSS feed lists and managing hierarchical data. The OPML file extension denotes XML-based documents that offer simplicity and interoperability in transferring structured information across diverse platforms. In essence, OPML serves as a versatile tool in the realm of data organization and syndication.
