# === Version History ===
# 2007-01-19: version 0.5, minor logging/UI tweaks
# 2005-10-25: released version 0.4
# 2005-10-25: fork post_to_delicious so we don't have to wait for a response (holy crap, I
#             can't believe it was broken this long without noticing!)
# 2005-08-24: added channel ignore, thanks to Rev. Jeffrey Paul
