Formats:
Currently only one format called "text" is supported:
\{\{ \}\} can be used to enclose inline verbatim text.\{\{\{ \}\}\} can be used to enclose verbatim text where whitespace is preserved.\ , \{\{ and \{\{\{. In inline verbatim text, special sequences are \ and \}\}. In verbatim text, special sequences are \ and \}\}\}.Character encoding: UTF-8 is strongly recommended, if not plain ASCII.
`Text is regular text. `Code is text that was enclosed within \{\{ \}\} and should be rendered using the same fixed-width font used in all verbatim text.
`Paragraph is a regular paragraph. `Pre is preformatted text that was enclosed within \{\{\{ \}\}\} and should be rendered using a fixed-width font preserving all space and newline characters.
A document is a list of paragraph-like blocks.
