 wired-in packages like <TT

you may need to use a more specific ordering for your versioning
scheme.  For example, some versioning schemes may include pre-releases
which have tags <TT

>&quot;pre2&quot;</TT

be taken into account when determining ordering.  In some cases, date
ordering may be more appropriate, so the application would have to
look for <TT

The bottom line is, don't always assume that <TT

>compare</A

> and other <TT
><A HREF="../base-4.2.0.2/Data-Ord.html#t%3AOrd"

possible concrete representation is provided (see <TT

<TT

representation may be more appropriate.
