[Groff] XHTML and epub

[Timothy Groves]

I have been trying to use groff to create the content files for epubs, 
and fbreader is refusing to read them.  I have tracked down a few bugs 
and squashed them, but still nothing seems to work.  So on the off 
chance that it's groff causing the problem, or my mis-use of groff, the 
command line that I am using is:

groff -Txhtml -U -s -ms manual01.ep > epub/OEBPS/Text/manual01.xhtml

where 'manual01.ep' is (obviously) my input file.  There are five such 
input files, each one written to a similarly-named output file in 
epub/OEBPS/Text.

In the event that my bug is in the content.opf or toc.ncx files, I shall 
continue to research them.  However, I am becoming convinced that it is 
not, as the navigation system works fine;  it's only the page content 
that does not render.
