Remember our dirty perl hacker and the graduate student who is supposed

Suppose it's written in C and hard-linked into the web server.
Suppose it was supplied by a commercial vendor, and changing or replacing
it invalidates the support contract for a $500,000 installation...

I don't believe this dogma :-)

I don't care. If it's the difference between
"our integration team can do this"
"our product development or serious programming team could do this"
it's the difference between succeed and fail.
So allow both, OK? Are you really so set against PIs here?
Is there a (non-religious) reason?
They could be significant comments if you prefer --
like httpd server side includes/execs... (ugh)
