It is time to make the package available to this group! I have updated
the package, zipped it up, transferred it to another system, installed
it and successfully built the rexxref, rxmath and readme documents. I
apologize for the size of the package - 33.2 MB - but most of that size
is due to FOP. I strongly recommend that after downloading it from here
<https://www.dropbox.com/s/s5d9mwx63xru1tk/orxbldoc.zip?dl=0> that you
first extract only the read1st.txt file. It will explain the
installation requirements as well as how to use it.
Just a couple of comments: as I have not attempted to build all of the
ooRexx documents, I suspect that there are still some "surprises"
lurking out there. I have not solved the "extra" levels issue in the TOC
but felt this was not a serious enough problem to delay making the
package available. And, of course, any questions, comments, criticisms
or suggestions for improvement are welcome.

I have added the templates to the pdf.xsl file I have been using and
deleted the call to fop-preprocess.rex. When I run the doc2fo and the
fo2pdf steps I get what appears to be the same result as when using
the fop-preprocess script! Here
<https://www.dropbox.com/s/oqx1wrddr75opk2/rexxref.zip?dl=0> is a link
to a zipped version in my Dropbox. I will proceed to update my package
and documentation and should have something available soon...

Wow! I had suspected it might be possible to accomplish the blank
line removal by modifying the stylesheet template for the
programlisting element but never got around to exploring what would
be required (and learning a lot more XSLT). I will add this to the
pdf.xsl file and give it a go.

Removal of unwanted leading/trailing whitespace from a DocBook
<programlisting> element with a "fop preprocessing" script was just
my bad hack and should be abandoned.
Please add the following code to the xsl style sheet - this should
take care of what we want. The script invocation should be removed.

The reason why I didn't just go through all our doc XML's and remove
unwanted whitespace from <programlisting>'s, is that it not only
would have been a lot of work, but it also would make the examples
more difficult to read or copy/paste (for the developer, not the
user) as the <programlisting> and CDATA markup would have to be all
on the same line as the first line of the example. I had changed a
few examples like this, but then didn't like it at all.
This still leaves us with quite a bit of unwanted whitespace from
our <indexterm>'s, but that's another story.
