DigiTemp v2.4 rrdb scripts

The Round Robin Database is a great way to store data that you want to
graph. You can get it from:
http://ee-staff.ethz.ch/~oetiker/webtools/rrdtool/
log_temps calls digitemp and adds the current temperature readings to the
RRD database. It should be called from a crontab at regular intervals.
log-temperature.pl is a Perl script that runs digitemp and inserts the
new samples into the RRDB, optionally it can create a text file for use
in an email signature.
make_temps creates a RRD database suitable for logging 3 sensors of data.
temp-all.cgi
temp-one.cgi are scripts to generate .png graphs of temperature data.
Insert them into your webpage with: <IMG SRC="temp-all.cgi">
temp-minmax.cgi generates a graph with minimum and maximum printed on the
graph.
The suggested initialization sets up digitemp to output the temperature in
Centigrade and the conversion to Fahrenheit. The -o option passed to
digitemp when it is initialized controls how the temperature is output.
