The reason that you haven't seen this tool before is that it's
theoretically meant for maintainer scripts in the same way that
"invoke-rc.d" is.

We, users, are supposed to use wrappers for these executables in the
same way that we're meant to use the adduser wrapper rather than
useradd.

"service" is a wrapper for "invoke-rc.d". Unfortunately "update-rc.d"
doesn't have a wrapper so you have to use it to enable/disable
sysvinit daemons.

The "update-rc.d" docs that you found opaque are most probably the
ones explaining the "start|stop" verbs and options and they're no
longer used and they're flagged as bugs when found in Debian
maintainer scripts.
