README.txt File Format
The whole text is converted to unix newline format before parsing.
Sections are separated by 3 newlines (two empty lines).
The first line of the section is its header.
When splitting the file to sections and headers, any leading or trailing
whitespace is removed.
If there is a single newline inside a section, it is converted to
space to enable correct wrapping.
If there are two consequent newlines, they are left as they are,
essentially making a paragraph break.
