Have you compared these files in SVN /trunk and the new /silver?
/trunk was originally created by a flawed procedure at
SourceForge which accepted the incorrect metadata from CVS
without question and was subsequently corrected, while /silver
was create by a complete different route. I am hoping that
the problem did not re-occur in /silver.

Yes, this is a known problem. Ralf Hemmecke posted the changes to
/trunk to correct this problem. It is necessary to correctly set
the properties in svn so that the files are not mangled.

I think it is a good example of the kind of patch that should be
"backported" into build-improvements as Gaby suggested in a previous
email. If we could do that it would possibly benefit users of the
Axiom4Sage package that I just created for Sage users. But this is
not critical since hyperdoc is not normally used through the Sage
interface.
