Mine looks like this:
[parameters]
id=ME@B.C
[networking]
keyserver=proxy80.teamanandtech.com
[rc5]
randomprefix=1
preferred-blocksize=33
fetch-workunit-threshold=512
[misc]
project-priority=RC5,DES=0,CSC=0,OGR=0
run-work-limit=0
[logging]
log-file-limit=100
log-file="C:\Program Files\distributed.net\rc5.log"
log-file-type=fifo
[triggers]
restart-on-config-file-change=yes
[buffers]
frequent-threshold-checks=3
threshold-check-interval=0:30
So, starting from the top, in the [Networking] section, fetch blocks from the TeamAnandTech servers (you get to see your stats there, updated every 15 minutes!) In the [Misc] section, do *only* RC5. In the [Logging] section, maintain a text file that logs the progress of the client. In the [Triggers] section, if I make a config change, the client will automatically reload itself. In the [Buffers] section, every 30 minutes, do a fetch & flush.
