To my understanding, cgilib-0.5's Makefile "install" operation
(i.e. "make install") does not install the library in a convenient
location (such as /usr/lib), but rather places the example CGI
executable "cgi-test" in /usr/lib/cgi-bin.
install: cgitest
install -m 755 cgitest /usr/lib/cgi-bin
My point is that you should just copy the generated library
manually and place it into /usr/lib.

It's certainly possible but you do not yet seem to understand the
framework you are working with.

Name and value are not bound to anything; they're just pointer
pointers that have yet to be assigned.
For CGI-BIN, parameters are passed to your program via environment
variables. For a reference, you may want to look here:
<http://hoohoo.ncsa.uiuc.edu/cgi/env.html>
The nice thing about the CGI libraries is they package up the
submitted parameters and place them nicely in variables, such as the
"name" and "value" variables mentioned above. If you do not want to
use one of theirs, you shall have to construct you own.
