Convert OPML to 7 (Man Page)

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.

The 7 file extension refers to Unix manual pages (man pages) in Section 7 of the Unix manual, which covers miscellaneous system information. These files, such as "boot.7", provide documentation on various system components and conventions. Historically, man pages have been a fundamental part of Unix-like systems, offering essential guidance for system administrators and developers. To view a 7 file, use the "man" command, e.g., "man boot".
