Recently upgraded from Redhat 8.0 to Fedora Core 1.0. So far, I love the new distribution. I use docbook and psgml to publish various docs, and tonight I attempted to use that for the first time since upgrading. When I attempted to validate my sgml in emacs (psgml), I got the following error: nsgmls:E: cannot open "/usr/share/sgml/docbook/sgml-dtd-4.2-1.0-14/docbook.dcl" (No such file or directory) I looked in the above-mentioned directory, and found that it contains an upgraded dtd - sgml-dtd-4.2-1.0-22.1. I have always been confused setting up docbook, but love it once it's working. I believe there is a catalog somewhere I need to update, but don't know where it is. Can someone provide some guidance on how to get docbook working on Fedora? Thanks! Bill Johnson "Call unto me, and I will answer thee, and shew thee great and mighty things that thou knowest not."
