REBOL can be embedded into other types of text such as
email messages, WEB pages, news groups, etc.

To do this, place the entire script, including the header
within a block [].  The REBOL word must be the first value
in the block.

For instance, to put a script into an HTML file, you can
use the SCRIPT tag.  Here's an example (this example may
not show up on some browsers... you may need to examine
the source).

(NOTE: Most browsers do not yet support evaluation of inline
REBOL code, but the following method is useful if evaluating
web pages within REBOL.)

<SCRIPT language="REBOL">

[
    REBOL [
        Title:  "REBOL Script in HTML File"
        Date:   24-Apr-1999
        File:   %inhtml.r
        Purpose: {
            Shows how to embed a REBOL subscript within an
            HTML document.
        }
        Category: [markup 1]
    ]

    print "REBOL spoken here!"
]

</SCRIPT>

;Of course, you only need the SCRIPT tag for WEB pages.
