Convert EPUB to 5 (Man Page)

The EPUB (Electronic Publication) file extension is a widely utilized format for digital books and publications, leveraging its versatility across various e-readers and devices. Officially established by the International Digital Publishing Forum (IDPF) in 2007, it superseded the Open eBook standard. EPUB's structure allows for reflowable content, meaning text can adapt to different screen sizes, enhancing readability. It supports multimedia elements, such as images, videos, and interactive features, making it suitable for diverse digital publications beyond conventional eBooks. EPUB's adoption stems from its open standard, promoting broad compatibility and ease of access in the digital publishing landscape.

The 5 file extension refers to Unix Section 5 Manual Pages, which document file formats and conventions used in Unix-like operating systems. These manual pages, accessible via the "man" utility, provide detailed information on system-level file formats, such as "deb.5" for the DEB file format. Historically, Section 5 has been a crucial resource for system administrators and developers to understand and manage various file formats and system conventions in Unix environments.
