DOCBOOK-APPS: ldb2pdf script that uses different stylesheets ...

Hi,

Here is a modification to the db2pdf script that comes with RedHat 7.0 ...
as part of the stylesheets-1.54 RPM.

This modification allows you to have a stylesheet with the same name as the
document sgml file in the directory containing the SGML source (if document
is called fred.sgml, the script looks for fred.dsl), but if that cannot be
found, the script looks for stylesheet.dsl in the same directory as the
source, otherwise it falls back to the default one.
