I've created on author index using the <OtherIndexes> envariable, and
<MultiPg>. I understand that I must explicitly define variables for
message-page navigation buttons ($NextButton$, etc.) for the index
of my new author index.
Unhappily, MHonArc does *not* support next/prev *message*
page links for any index defined via the <OtherIndexes>
I asked the same question a couple of months ago...
Perhaps this should be mentioned in the <OtherIndexes>
