Seems to fix bug 1649.

It seems that for a given Apache child, the first run of tth would blow
up and spit out an error message, but not kill the child. The second run
would then totally kill tth (it output nothing at all, not even an error
message, let alone the HTML-ified tex), and only then would the server
die.

Usage: texxml2indextex.pl texxmlfilename
texxml2indextex.pl will create an 'index file' suitable for use as a 
sort of title page for a given set of help files. The second file will
be placed at the beginning, verbatim, so it can be used to provide
context, title, etc, if given.
