Convert OPML to RST

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 RST file extension stands for reStructuredText, a lightweight markup language widely used for technical documentation. Originally developed as part of the Docutils project in 2001, reStructuredText facilitates the creation of readable plaintext documents that can be easily converted into various output formats such as HTML, PDF, and LaTeX. Its clear syntax and straightforward conventions make it a preferred choice for documenting software projects, especially within the Python community. RST files serve a crucial role in maintaining accessible and well-structured documentation, ensuring consistency and simplicity in formatting across different platforms.
