-file*
-.SH "DESCRIPTION"
-\fBcmark\fR
-converts Markdown formatted plain text to either HTML, groff man,
-CommonMark XML, LaTeX, or CommonMark, using the conventions
-described in the CommonMark spec.  It reads input from \fIstdin\fR
-or the specified files (concatenating their contents) and writes
-output to \fIstdout\fR.
-.SH "OPTIONS"
-.TP 12n
-.B \-\-to, \-t \f[I]FORMAT\f[]
-Specify output format (\f[C]html\f[], \f[C]man\f[], \f[C]xml\f[],
-\f[C]latex\f[], \f[C]commonmark\f[]).
-.TP 12n
-.B \-\-width \f[I]WIDTH\f[]
-Specify a column width to which to wrap the output. For no wrapping, use
-the value 0 (the default).  This option currently only affects the
-commonmark, latex, and man renderers.
-.TP 12n
-.B \-\-hardbreaks
-Render soft breaks (newlines inside paragraphs in the CommonMark source)
-as hard line breaks in the target format.  If this option is specified,
-hard wrapping is disabled for CommonMark output, regardless of the value
-given with \-\-width.
-.TP 12n
-.B \-\-nobreaks
-Render soft breaks as spaces.  If this option is specified,
-hard wrapping is disabled for all output formats, regardless of the value
-given with \-\-width.
-.TP 12n
-.B \-\-sourcepos
-Include source position attribute.
-.TP 12n
-.B \-\-validate-utf8
-Validate UTF-8, replacing illegal sequences with U+FFFD.
-.TP 12n
-.B \-\-smart
-Use smart punctuation.  Straight double and single quotes will
-be rendered as curly quotes, depending on their position.
-\f[C]\-\-\f[] will be rendered as an en-dash.
-\f[C]\-\-\-\f[] will be rendered as an em-dash.
-\f[C]...\f[] will be rendered as ellipses.
-.TP 12n
-.B \-\-unsafe
-Render raw HTML or potentially dangerous URLs.
-By default, raw HTML is replaced by a placeholder comment
-and potentially dangerous URLs are replaced by empty strings.
-Dangerous URLs are those that begin with `javascript:`,
-`vbscript:`, `file:`, or `data:` (except for `image/png`,
-`image/gif`, `image/jpeg`, or `image/webp` mime types).

-When there is no child, the iterator will go to the next sibling.
-When there is no next sibling, the iterator will return to the
-parent (but with a \f[I]cmark_event_type\f[] of
-\f[C]CMARK_EVENT_EXIT\f[]). The iterator will return
-\f[C]CMARK_EVENT_DONE\f[] when it reaches the root node again.
-One natural application is an HTML renderer, where an
-\f[C]ENTER\f[] event outputs an open tag and an \f[C]EXIT\f[]
-event outputs a close tag. An iterator might also be used to
-transform an AST in some systematic way, for example, turning all
-level\-3 headings into regular paragraphs.
