hmm - thanks for the reminder.

I overlooked that in migrating the site: in the original site, I constructed
a symbolic link from the breakout directory to the (partly generated)
help-directory, e.g.,

  http://lynx.invisible-island.net/release/lynx_help/cattoc.html
 
But in the current site, links like that are harder to generate :-)

right - I don't think it's worth the trouble (patches and tarballs work).

Mostly it seems that I should tidy up the old release breakouts
to repair broken links.  (I'll work on that - but bear in mind
that they'll cite the old hostnames).

But the discussion began with the development sources and the package.
