- h1: String Manipulation

- p: SSGen has helpful directives for manipulating strings
- p: >
    The <code>!SUBSTRING</code> directive takes a substring (duh).
    The first two arguments are the bounds, and the third argument
    is the YAML that gets parsed before being cut.

# Example
- span:
    _class: two-column-grid-with-spacer
    yaml:
      - !DEF [NAMED_CODE_NAME, "<i>input_directory</i>/index.page"]
      - !DEF
          - NAMED_CODE_CONTENT
          - |

              &lt;p&gt;Para&lt;/p&gt;
             &lt;/body&gt;
            &lt;/html&gt;
      - !INCLUDE /blocks/named-code.block
