As discussed in /_posts/2017-01-03-pdp-11-tutorials.md, when a page (usually part of a tutorial)

using a Liquid-style include that looks like:

{% include machine-command.html type='button' label='Try It!' machine='vt100' component='Keyboard' command='sendString' value='Hello World' %}

and which should generate something like this:
<button type="button" onclick="commandMachine('vt100','Keyboard','sendString','Hello World')">Try It!</button>
Well, that's us. So let's do it!
Alternatively, if the command parameter is the name of a command string in the page's Front Matter, then this:
{% include machine-command.html type='button' label='Try It!' machine='vt100' component='Keyboard' command='scriptName' %}
should generate something like this:
<button type="button" onclick="commandMachine('vt100','Keyboard','script','...')">Try It!</button>
{% endcomment %}
{% if include.type == "button" %}<button type="button" onclick="commandMachine('{{ include.machine }}','{{ include.component }}','{{ include.command }}','{{ include.value }}')">{{ include.label }}</button>{% else %}<!-- Unrecognized machine control type: {{ include.type }} -->{% endif %}
{% if page.commands[include.command] != nil %}{% assign machine_command = "script" %}{% capture command_value %}{{ page.commands[include.command] | replace:'"','&quot;' }}{% endcapture %}{% else %}{% capture machine_command %}{{ include.command }}{% endcapture %}{% capture command_value %}{{ include.value }}{% endcapture %}{% endif %}{% if include.type == "button" %}<button type="button" onclick="commandMachine('{{ include.machine }}','{{ include.component }}','{{ machine_command }}','{{ command_value }}')">{{ include.label }}</button>{% else %}<!-- Unrecognized machine control type: {{ include.type }} -->{% endif %}
