<!-- The following characters could not be defined using commonly available
fonts. Therefore, EBT is using placeholders for these characters. To include
the placeholders in your document, make sure that the marked section below has
the keyword "INCLUDE".

To ignore the placeholders, use the keyword "IGNORE". If you are ignoring this
marked section and your SGML document references any of the entities declared
below, you will get (non-fatal) mkbook errors, and the entity references will
not be replaced.

Finally, you may choose to define the entities below yourself, using a special
font that will be available to readers of your DynaText books. Use the same
SDATA entity declaration model as is used above, substituting the appropriate
names and decimal numbers for font, charset, code, and descr. In that case, you
should INCLUDE the marked section.
