Convert LATEX to FB2

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.

The FB2 file extension stands for FictionBook 2.0, a popular XML-based eBook format. Initially developed in Russia for easy parsing and conversion across different eBook readers, it preserves metadata and structure effectively. FB2 is mainly used for fictional literature, allowing detailed descriptions of text formatting, titles, and subtitles, which enhances the user reading experience. Its open-standard nature ensures broad compatibility and ease of modification, making it a preferred choice in digital publishing.
