- h1: Advanced

- p: SSGen has advanced features that must be explicitly enabled
- p: >
    The <code>!SHELL_CMD</code> directive executes a shell command,
    and is enabled with the <code>--enable-shell</code> flag.
    The output is taken from stdout and is pasted unparsed into the document.

# Example
- span:
    _class: two-column-grid-with-spacer
    yaml:
      - !DEF [NAMED_CODE_NAME, "<i>input_directory</i>/index.page"]
      - !DEF
          - NAMED_CODE_CONTENT
          - |
            html:
              body:
                h1: Title
                p:
                  !SHELL_CMD [echo, Hello, Echo]
      - !INCLUDE /blocks/named-code.block
    br: ''
    html:
      - !DEF [NAMED_CODE_NAME, "<i>output_directory</i>/index.html"]
      - !DEF
          - NAMED_CODE_CONTENT
          - |
            &lt;html&gt;
             &lt;body&gt;
              &lt;h1&gt;Title&lt;/h1&gt;
              &lt;p&gt;Hello Echo&lt;/p&gt;
             &lt;/body&gt;
            &lt;/html&gt;
      - !INCLUDE /blocks/named-code.block

# Clarification
- p: Enable and use these features at your own risk!
- p: Well technically the whole program is run at your own risk...
