This is the default parser used by Text::Markdown in the event that it cannot determine the format of a
text file. All it does is read the file in (relying on a BOM
<https://www.unicode.org/unicode/faq/utf_bom.html#BOM>, encodes all entities, and then returns an HTML
string with the file in a "<pre>" element. This will be handy for files that really are nothing but plain
text, like README files.
By default this parser is not associated with any file extensions. To have Text::Markup also recognize
files for this module, load it directly and pass a regular expression matching the desired extension(s),
like so:
use Text::Markup::None qr{te?xt};
Normally this module returns the output wrapped in a minimal HTML document skeleton. If you would like
the raw output without the skeleton, you can pass the "raw" option to "parse".
