Certainly. It comes attached with caveats: to wit, it's a brutal
kludge. It works for me, for the GCC HOWTO, but don't expect it to
work in the general case without checking the output it produces.
The way I use it is to insert
<index "chewing gum">
at the point that I want an index entry for `chewing gum' (the
intention is that you can have arbitrary markup as well, but this
doesn't work for anything other than the cases that `sub textof'
deals with) and
<PRINTINDEX>
at the end of the document. I'll probably keep playing with it as I
find new things for it to do, but for anyone who finds it useful in
its current form, this is the thing.

I intend to give the ELF HOWTO an index in its next version (mainly
for the practice), so that might knock out a few more oddities
