Make sure that only one intro is included in the integrated doc.
Multiple intros cause trouble since they have some section elements (e.g. "y2k.sgml") in common leading to duplicate labels.Include emacs formatting hints in the intro*.sgml sources.

Traditional relational database management systems
25-
(DBMSs) support a data model consisting of a collection
26-
of named relations, containing attributes of a specific
27-
type. In current commercial systems, possible types
28-
include floating point numbers, integers, character
29-
strings, money, and dates. It is commonly recognized
30-
that this model is inadequate for future data
31-
processing applications.
32-
The relational model successfully replaced previous
33-
models in part because of its "Spartan simplicity".
34-
However, as mentioned, this simplicity often makes the
35-
implementation of certain applications very difficult.
36-
<ProductName>Postgres</ProductName> offers substantial additional
37-
power by incorporating the following four additional
38-
basic concepts in such a way that users can easily
39-
extend the system:

<SimpleList>
42-
<Member>classes</Member>

46-

47-

63-
from those referred to as <FirstTerm>object-oriented</FirstTerm>, which in general
64-
are not as well suited to supporting the traditional relational database languages.
65-
So, although <ProductName>Postgres</ProductName> has some object-oriented features,
66-
it is firmly in the relational database world. In fact, some commercial databases
