Again, I think we should just provide a way to -ask Mercurial where it
thinks the templates are-. Like this:
$ hg debuginstall
Checking encoding (UTF-8)...
Checking installed modules (/home/mpm/hg/mercurial)...
Checking templates (/home/mpm/hg/mercurial/templates)...
Checking commit editor...
This is infinitely more reliable than any manual procedure we could
document. I'll go ahead and push the patch I wrote to add this little

This file is a thin, static skeleton:
and the hg.1.gendoc.txt is the auto-generated content.
Mathematics is the supreme nostalgia of our time.
