Convert FB2 to TEXT HADDOCK

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.

The TEXT file extension, associated with Haddock Markup Language, is used for documentation in Haskell programming. Haddock is a tool for generating documentation from annotated Haskell source code. It uses a lightweight markup language, similar to LaTeX, to format the documentation. The history of Haddock dates back to its creation by Simon Marlow and others as part of the GHC (Glasgow Haskell Compiler) project. It has since become a standard tool in the Haskell community for creating comprehensive and readable documentation.
