Fiddling around with nanoblogger's templates and
Haloscan code. In other words, breaking stuff to try to get them to
work well together.
Update: once I figured out the variables, I added this line to
entry.htm, and it works with haloscan:
$([ "$PERMALINKS" = "1" ] && echo '| Trackback')
Heh. So of course the variable NB_EntryID got expanded in the
explanation.
