This documentation would be very helpful.

I think the checks we will be doing in the configure scripts for
ScrollKeeper and the GNOME packages will be:

A) xmlcatalog /etc/xml/catalog "-//OASIS//DTD DocBook XML V4.1.2//EN"

and

B) xmlcatalog /etc/xml/catalog
http://docbook.sourceforge.net/release/xsl/current/html/chunk.xsl

[we will also test for the existance of libxml2-devel (for xml2-config),
libxslt (for xsltproc), and maybe some other stuff]

So, if you want to check out if your distribution has things set up
properly:

1) make sure you have a recent libxml2 (b/c you need xmlcatalog),
xsltproc, and xml2-config
2) make sure you have docbook-dtd412-xml and docbook-style-xsl installed.
3) make sure commands (A) and (B) above return "file:///" followed by a
path, and not "No entry for ...".
4) make sure the two files returned by (A) and (B) actually exist on your
machine

If you have everything installed and it doesn't work right, you should
upgrade your packages.  If they are up-to-date, you may consider
contacting the packager of docbook-dtd412-xml and/or docbook-style-xsl
for your distribution and ask them to verify the catalog registration is
being done properly.
