This repository is a book project titled 'Metaprogramming: Multi-paradigm approach in Software Engineering' by Timur Shemsedinov. It contains extensive educational content in multiple languages (English, Russian, Czech, Ukrainian, German) stored as Markdown files. The repository includes a Node.js build script that uses pdfmake to generate PDF versions of the book from the Markdown sources. The build system is simple but well-structured, leveraging metavm for configuration and pdfmake for PDF generation. The book covers programming paradigms, data structures, algorithms, and software engineering concepts with code examples in JavaScript, Python, C, and other languages. This is primarily a content repository with a build tool, not a reusable software library or data pipeline.
