 <p>Org-transclusion lets you insert a copy of text content via a file link or ID link within an Org file. It lets you have the same content present in different buffers at the same time without copy-and-pasting it. Edit the source of the content, and you can refresh the transcluded copies to the up-to-date state. Org-transclusion keeps your files clear of the transcluded copies, leaving only the links to the original content.<span id="whatis"></span></p>
