These are the scripts and data files used for the monthly statistics
of the principal IRC channels and mailing lists statistics associated
with the Qi-Hardware project.
Monthly process:
IRC:
./collect
./stat
display out.png
qippl out.png stat/irc-qihw-MMYY.png
Mailing lists:
# update ML from archive pages
./mlstat
qippl out.png stat/ml-qihw-MMYY.png
MMYY is the last full month covered.
