.Sh DESCRIPTION
.Nm
is a utility to transpile

formatted plain\-text files into valid HTML and XML.
Files provided as command\-line arguments will be transpiled with the result
being written to the standard output.
If no arguments or the special filename

is provided, then input will be read from the standard input.

By default files are transpiled to HTML, where tags with no children take the
form of
.Ql <tag>
as opposed to XML where they take the form of
.Ql <tag/> .
If the document begins with an XML document type, then
.Nm
will transpile to XML.
