The <<include-part>> macro is a simple extension of SugarCube's built-in <<include>> which includes part of another passage instead of the whole thing.
Warning
Version 1 of this macro incorrectly ran SugarCube code present in the parts of the passage you were not including. Version 2 does not do this. If you are using version 1, you should upgrade.

<<include-part "passage" "#target" [remove-container|boolean]>>
Include part of the passage given in the first argument into the current passage. The second argument is treated as a selector to identify which element to include. If the optional third argument is true then only the children of the selected element are included, if it is false (the default) then the selected element is also included.
Passage1
<<include-part "passage2" "#target">>Passage2
Some text.
Some other text.
<span id="target">Text to be included.</span>
Yet more text.In this example, only the span with the id target gets included in Passage1. If the third argument was true (<<include-part "passage2" "#target" true>>) then only the text inside the span would be included in Passage1.
