The DocBook DTD defines structural and content-based SGML markup
for computer documentation, with a primary emphasis on software
documentation and related classes of technical documents. Its
main high-level hierarchical structures are for books, reference
entries (for example, ``man pages''), and articles. It is
maintained by the DocBook Technical Committee of OASIS.

This port contains DocBook 4.0 BETA 5.
