I'm sorry we don't have more manual pages here.  Just ran out
of time and energy.  Here are a few tips:

Most of the stuff included here has been changed to know about
something, like quotas, overlays, or the new tty driver.
Often the manual page would not have changed.  Programs like
strip, file, size have the same usage as before.  The cc command
has one new option, -V, to use for overlays.  The makefile for
ex is included as an example of how to use overlays.
