# Based on commentcount.pl.

# (1.1) Tweaked things to accomodate FCKEditor which seems to garble the header. We now introduced the minor bug that a first comment with the phrase 7 Comment will be updated with each comment. Oh well. This should almost never happen. 

# (1.0) 
# - changed comment marker to === $num comments === to look better since ### triggers a number list with creole, and it now makes a nice header
# - link now reads "Comments on page ($num so far)"
