| 1543 | text, however by wrapping the results in an org code |
| 1544 | block they can be replaced upon re-execution of the |

| 1552 | This is a good option if you code block will output |
| 1553 | latex formatted text. |
| 1554 | |
| 1555 | code ---- the results are extracted in the syntax of the source |
