Purpose: {a parsing exercise}
Note: {
The parsed and displayed documents may edited and then saved by the reader.
Reversing the process might be used to produce HTML documents.
Loading "REBOL [" is an issue in this arrangement, so "REBOL [" is changed to "r-ebol [",
and later, changed back to "REBOL [".
No reliance on the parsed Rebol documents portrayed in this script can be made.
This script is an exercise in parsing. There is no representation of the
accuracy or otherwise of the material converted from the source HTML documents.
Use only official REBOL documentation.
Comments may be made directly from the local documents.
