In avionics, it is of utmost importance to write the right documents. After having done the planning documents, you will need to write the Software Requirements Document (SRD). Sol was designed with this process in mind. As a result, Sol is a format designed to write technical documents, in human-language. It has headings, content, markup like bold or italics, bullets and lists, hyperlinks, and more features for writing technical documents. Avionics is also all about configuration management, and change tracking. For this reason, while the Sol development environment shows you the text with full markup, Sol stores the information in a plain text format. As a result, version control systems can easily track the changes in the documents. Authors can use branch and commit histories, and see who made what change to the document when. Because Sol uses a pure-text format, it does not require special databases or servers. Finally, because Sol is an easy to parse text format, you can integrate Sol with your organization's processes using scripting.
