Only that we will be dealing with _another_ lazy boss who thinks just because
the tool indicates it is bad that it is.  These bosses are lazy because they do
not want to spend the time to have the programmers understand each others code
(peer review), and manage the fact that you will occasionally get a programmer
who is a back biter.

hey, if the problem is small enough to solve in a week fine, however being
forced to checkin code which may not be functional or may not be fully
functional and then justify it, is only disruptive.

Again only a manager who is lame brained (wait how many does than not describe)
would still look at lines/words/bytes instead of functionality added or bugs

Ok, this might make some sense, however peer review is better from the
perspective of most rules have some point where they break down in the
readability/maintainability of the code.

again, peer review still does this better and saner.

Unless your scripts can check all of the functionality of the system or show
you which trouble reports were fixed, it is pretty useless.  Better to check
the commit comments and make the programmer put in something useful that can be
tracked back to the requirements or trouble reports, so you can use something
like to generate your reports to your boss.

If your programmers are any good the things you mention above will not be
valuable for measuring progress, you should be measuring system functionality
and how well the programmers estimate time for adding functionality and fixing

I suppose that we should take any further discussion of this off list.

I'd crawl over an acre of 'Visual This++' and 'Integrated Development
That' to get to gcc, Emacs, and gdb.  Thank you.
