How can I show only the introtext or fulltext of the description?

When using the Joomla system "Read More" separator within the Location Description field, you can use {description}, {introtext} and {fulltext} in your Address Templates as follows

{description} : Includes introtext + fulltext unless "Show only introtext of description" is set to yes.  In that case, it is only {introtext}

{fulltext}: Includes only text after the system "Read More"

{introtext}: Includes only text before the system "Read More"
