# mdman(1)
## NAME
mdman - Converts markdown to a man page
## SYNOPSIS
`mdman` [_options_] `-t` _type_ `-o` _outdir_ _sources..._
## DESCRIPTION
Converts a markdown file to a man page.
The source file is first processed as a
[handlebars](https://handlebarsjs.com/) template. Then, it is processed as
markdown into the target format. This supports different output formats,
such as troff or plain text.
Every man page should start with a level-1 header with the man name and
section, such as `# mdman(1)`.
The handlebars template has several special tags to assist with generating the
man page:
- Every block of command-line options must be wrapped between `{{#options}}`
and `{{/options}}` tags. This tells the processor where the options start
and end.
- Each option must be expressed with a `{{#option}}` block. The parameters to
the the block are a sequence of strings indicating the option. For example,
```{{#option "`-p` _spec_..." "`--package` _spec_..."}}``` is an option that
has two different forms. The text within the string is processed as markdown.
It is recommended to use formatting similar to this example.
The content of the `{{#option}}` block should contain a detailed description
of the option.
Use the `{{/option}}` tag to end the option block.
- References to other man pages should use the `{{man name section}}`
expression. For example, `{{man "mdman" 1}}` will generate a reference to
the `mdman(1)` man page. For non-troff output, the `--man` option will tell
`mdman` how to create links to the man page. If there is no matching `--man`
option, then it links to a file named _name_`.md` in the same directory.
- Variables can be set with `{{*set name="value"}}`. These variables can
then be referenced with `{{name}}` expressions.
- Partial templates should be placed in a directory named `includes`
next to the source file. Templates can be included with an expression like
`{{> template-name}}`.
- Other helpers include:
- `{{lower value}}` Converts the given value to lowercase.
## OPTIONS
<dl>
<dt class="option-term" id="option-mdman--t"><a class="option-anchor" href="#option-mdman--t"></a><code>-t</code> <em>type</em></dt>
<dd class="option-desc">Specifies the output type. The following output types are supported:</p>
<ul>
<li><code>man</code> — A troff-style man page. Outputs with a numbered extension (like

<li><code>md</code> — A markdown file, after all handlebars processing has been finished.
Outputs with the <code>.md</code> extension.</li>
<li><code>txt</code> — A text file, rendered for situations where a man page viewer isn't
available. Outputs with the <code>.txt</code> extension.</li>
</ul></dd>
<dt class="option-term" id="option-mdman--o"><a class="option-anchor" href="#option-mdman--o"></a><code>-o</code> <em>outdir</em></dt>
<dd class="option-desc">Specifies the directory where to save the output.</dd>
<dt class="option-term" id="option-mdman---url"><a class="option-anchor" href="#option-mdman---url"></a><code>--url</code> <em>base_url</em></dt>
<dd class="option-desc">Specifies a base URL to use for relative URLs within the document. Any

be used.</dd>
