Follow up: Are most of these read/write? Are there any that are by definition read-only? If so, could someone in the know point those out and I will get with Ray to make sure that we get the channel variables wiki page is updated.

I then filtered out stuff with svn in the source filename and then create a tab-separated list of chan variables and source filenames. Finally, I distilled that list with this script: perl -n -e 'm/(\w+)\t(.*)/;next if (exists($seen{$1}));print $1 . "\t" . $2 . "\n";$seen{$1}=$2;' /tmp/chan_vars3.tmp This yielded a nice list of variables.
