Install Python if necessary.

Install ConTeXt. Upgrading to a recent ConTeXt can be troublesome. Read carefully the recommendations available at http://wiki.contextgarden.net. At least you need to:

Install the XSLT. By default xsltproc is used.

Install the XML DocBook DTD.

Create a catalog file, that defines where to find the DTD. Here is an example:

PUBLIC "-//OASIS//DTD DocBook XML V4.1.2//EN" 
    "file:///usr/local/share/xml/docbook/dtd/4.1.2/docbookx.dtd"
    

If the XML Gnome tools are available, it's a good idea to create an XML catalog by using xmlcatalog such like this:

% xmlcatalog --noout --create mycatalog
% xmlcatalog --noout --add 'public' '-//OASIS//DTD DocBook XML V4.1.2//EN' \
                           'file://path/to/4.1.2/docbookx.dtd' mycatalog
    

Add the catalog path to the SGML_CATALOG_FILES variable:

export SGML_CATALOG_FILES=$SGML_CATALOG_FILES:/path/to/mycatalog

You can skip this step if you configure the installation with the --catalogs option.

Untar the ball. For a bzipped release, do as follow:

% bzip2 -dc dbcontext-x.x.x.tar.bz2 | tar xvf -

For a gzipped release, do as follow:

% gunzip -c dbcontext-x.x.x.tar.gz | tar xvf -    

Install the package. You can specify the base directory with the --prefix option. You can also use the --catalogs option to specify where the catalogs are.

% cd dbcontext-x.x.x
% python ./setup.py install --prefix=/usr/local --catalogs=/path/to/mycatalog

To know the other standard Python setup.py options, use the --help option.
