A driver program is something that calls the routines in the library
from the command line. Its usage was common in Computing Science in
the 1970s. You kids.
I wasn't aware that bozo required inetd - indeed, I used to run it from
the command line on a number of systems.

I was thinking more of an event driven system, like libevent or libev.
But that kind of usage would mean that the requirements for bozohttpd
just got much, much larger than before.

(For the rationale behind counting the number of semicolons at the end
of line being a non-commented line of code, I refer the honourable
gentleman to some speaker at a Unix conference from the 80s or 90s - I
think they were from Bell Labs. I realise that this doesn't narrow it

Not sure how it performs.
