Can we come up with a better name for this parameter? I'm thinking --sleep-interval or --polling-interval or something more descriptive?

Secondly, commander allows setting defaults which would save a little code later on, eg:

Suggested change
.option('-s, --sleep', 'Sleep interval in milliseconds between runs in daemon mode (default 10 * 60 * 60 * 1000 [ms] = 10 hrs)')
.option('-s, --sleep', 'Sleep interval in milliseconds between runs in daemon mode', 10 * 60 * 60 * 1000)

There are even more complicated options if you want to parse the variable or provide a human readable default value. More info in their documentation.

.option('-v, --verbose', 'verbose logging')
.action(function(source, target) {
couchdbUrl = source;
