Introduction to DocBook-3.1 SGML DTD

The DocBook SGML DTD package contains document type definitions for verification of SGML data files against the DocBook rule set. These are useful for structuring books and software documentation to a standard allowing you to utilize transformations already written for that standard.

This package is known to build and work properly using an LFS 12.1 platform.

Note

The package source is distributed in zip format and requires unzip (or bsdunzip from libarchive). You should create a directory and change to that directory before unzipping the file to ease the removal of the source files after the package has been installed.

sed -i -e '/ISO 8879/d' \
       -e 's|DTDDECL "-//OASIS//DTD DocBook V3.1//EN"|SGMLDECL|g' \
       docbook.cat

This package does not come with a test suite.

Now, as the root user: 

install -v -d -m755 /usr/share/sgml/docbook/sgml-dtd-3.1 &&
chown -R root:root . &&

install-catalog --add /etc/sgml/sgml-docbook-dtd-3.1.cat \
    /usr/share/sgml/docbook/sgml-dtd-3.1/catalog &&

install-catalog --add /etc/sgml/sgml-docbook-dtd-3.1.cat \
    /etc/sgml/sgml-docbook.cat
