Use the DocBook 4.1 DTD instead of 3.1.  Seems to work fine...

Give the book an id so it gets a nice HTML filename

Split the entities and the top-level book out into separate files, so
we can compose this book as part of a set.

Kill the libraries chapter, and move the material on
<literal>PrelGHC</literal> into the section on language extensions.

Wrote 4.06 release notes and updated version numbers in the rest of the user
guide.

Added binary installation chapter to user guide, made from old installation
guide and Sigbj?rn Finne's Windows installation page.

Libraries documentation moved to hslibs tree.

Retagged <Literal>s into <Filename>, <Option>, <Command>, &c.

VSGML files changed back to plain SGML during change from LinuxDoc to DocBook.
